Pros: Good quality, perform as claimed.
Cons: None.
Overall Review: Over the past few years I have purchased over 50 of these drives; some for myself and others for customers. So far (as of January 2021) there have been zero problems with them. If you're wanting low-cost backup drives, this product is a good choice.
Pros: PROS: Nice package; compact and lightweight.
Cons: CONS: I own 2 other battery packs very similar to this one, but different brand and lower rating (26,000 mAh, and 24,000 mAh). This one claims to be 50,000 mAh but loses its charge faster than either of the other ones with identical load. This one also takes longer to charge than the 2 with lower capacity. That is expected, except for their claim of "Recharges in 6 hours with a 2A adapter". It in fact takes almost 12 hours of charge time with a 2A adapter (tried 3 different adapters). The sales page claims "The Black Edition is able to provide 2.5 charges for Samsung Galaxy S6", but ran down almost completely after only 2 charges when the S6 still had 50% capacity. The other 2 lower capacity battery packs I mentioned, 26,000 mAh and 24,000 mAh, easily charge the S6 five times when the S6 is at 50% capacity.
Overall Review: I only give 2 stars, rather than 1, because of the low cost of the device. I think of it as having received a 16,350* mAh battery pack for a reasonable cost. If the sales page would have been honest in their claims, I would have given it a higher rating. I would not recommend this product because higher capacity products are available for just a few dollars more. *For reference: I measured capacity for these devices based upon the methods specified at the University of Michigan Energy Institute. That does not mean that the measurements were "perfect", but because I used identical setups for all 3 battery packs, the results provide a good relative baseline.
Pros: This item performs as stated. It is simple and it works.
Cons: None.
Overall Review: At least one person wrote "does not work on any usb with any hard drive even low wattage SSD" However, that makes no sense. a USB 3.0 port can supply up to 4.5 watts. Older USB 2.0 ports can supply up to 2.5 watts. A typical 2.5" SATA drive may require 1.6 watts, but during normal operations is closer to 1.3 watts. There is absolutely no problem with "powered by USB" in most cases. You should, of course, verify the rated power requirements of any device you intend to connect via this or any similar adapter cable.
Pros: Ample memory and internal disc, smooth performance, beautiful display, almost no bloatware pre-installed, easy to set up.
Cons: Has McAfee trial version pre-installed. Has Norton Backup pre-installed. The power connector is a right-angle type, and it connects immediately beside the DVD tray. If the cable is not positioned toward the rear of the computer, the DVD tray can not open. It is not a critical flaw, but for anybody who does not pay attention to such things, there is the potential to damage the DVD tray.
Overall Review: I would not recommend this as a gaming machine, because the Intel Celeron 2957U is not a high-performance CPU. But for average work, browsing, email, photo editing and other general tasks, this computer is a very good value. Initial setup was particularly easy, partly because Acer pre-installs almost no bloatware. The computer was easy to secure, easy to configure a custom log-on screen, and easy to create media for a "emergency restore" if ever needed. If you need/want a notebook computer but can not spend a lot of money, I recommend this model.
Pros: Compact, ample storage space, great price.
Cons: None.
Overall Review: I've noticed many posts here comment about this device being slow. I've had this one since June 2012 and have used it on several different computers. One observation I have made is that it is somewhat slow on *some* systems, depending on what anti-virus/anti-malware application is installed. Also, on Windows Vista if I copy via Windows Explorer, the transfer rate is only about 6MB/second. But on the same machine, I see about 14MB/second when I use "Replicator" to copy files. Windows Explorer is a little faster on XP and on Windows 7, than on Vista......not sure why. On computers running Symantec, AVG or TrendMicro, file transfers are consistently MUCH slower than on similar systems running different AV products (Kaspersky, ESET, MSSE).
Pros: Plenty of memory, disk space, good performance. The "instant on" feature is nice, when it works.
Cons: Keyboard is poor quality. Asus tech support is USELESS. The computer is LOADED with crapware. In my opinion at least 15 applications should be removed upon initial setup.
Overall Review: This is my 2nd one of this same model. The 1st was bought in Feb.2012 and works well. This new one was bought May.2012 and has many problems. The only physical problem is the poor keyboard. It is not the same keyboard as the one from February....is poor quality now. MAJOR ISSUES: Blue-screen crashes, Asus Live Update tries to update itself but crashes midway though the process. Machine randomly goes into extreme SLOW mode, will not run properly until rebooted. Rebooting takes over 10 minutes at best, sometimes much longer. My initial contact with Asus was not even responded to. Newegg helped with that, but when Asus finally responsed they addressed only ONE issue I wrote about and ignored others. Since that contact I have been unsuccessful in reaching them again. When I phone, they tell me the same thing: Restore the system and try again. My previous Asus (same model) was not loaded with all the crapware this one has. I am extremely disappointed with this purchase.
Pros: Lots of storage, simple to use, reliable.
Cons: No power switch. Slow to start.
Overall Review: I have owned 2 of these devices since June 10th 2011 (today is November 6th 2011), and use them a few times a week with different computers. So far, never a glitch. I've seen them on special for $89, which is really a bargain. I see some posts on here about reliability issues.....maybe I'm just lucky, but so far these devices have been solid performers. I wish they had a on/off switch, but it's not really a problem. They sense when they are connected, and power up at that point in time. These Hitachi devices are SLOW to start, taking about 8 to 10 seconds longer than most other external USB drives. I own and use many external USB drives, from Western Digital, Seagate, Buffalo, LaCie, and others. They all have good points and bad points. The slow startup is the bad point, in my opinion, for these Hitachi drives. Also note that, as with many brands of external drives these days, there is software already installed on them, for their own method of performing backups. Delete it!
Pros: Good storage capacity, fair price, nice case.
Cons: Data transfers are slower than other USB drives on same systems. I bought 2 new drives, and own 2 more from last summer (it is March 31 2011 now). The older devices, like my Western Digital and Maxtor external USB drives, average from 14 to 24 MB/sec transfers, depending on the data and the host. Both these new drives average from 4 to 6 MB/sec on same platforms. I tried a better quality USB cable (the new drives include the thinnest USB cables I've ever seen), but it appears to make no difference. The average consumer would be better off without the included Seagate software, which attempts to install itself upon 1st connection. Each package has FOUR different serial numbers! I've tried to get Seagate to explain which is the correct number to use for product registration, but so far it has only become more confusing. This is very annoying! At the Seagate product registration page, the pictures of "How to find the serial number" are incorrect. Their KB update is wrong too.
Overall Review: NOTE that the KB update mentioned above is available at: http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=215051 I'm very disappointed at the slow throughput of data on these new devices, as well as the high overhead of the formatting. It is called a "2TB" device (2000 gigabytes), but in fact is only 1.8TB of usable space. Why does their formatting waste 200 GIGABYTES OF DRIVE SPACE?!? Based on the Seagate forum pages, these devices are not very reliable. I guess I am lucky; no failures yet. But there are SO many posts on the support forum pages indicating a high rate of drive failures and/or data loss. In my opinion, Seagate is really slipping.
Pros: Large screen, HD format (which is what I was looking for), no stuck/dead pixels.
Cons: SLOW, poor manuals, heavy, SLOW, worst speakers/audio ever, poor quality images from cam, SLOW, excessive loss of storage space due to formatting (or something?).
Overall Review: To sum up this machine, the word SLOW is best. A sticker on the front boasts "8 second boot-up with Express Gate", but it really takes 34 to 35 seconds, consistently (still better than Vista). BUT... the Express Gate software is useless. The broswer can't find the internet, though a number of wireless points exist, all of which Vista finds connects with easily. A 320GB disk?? not really. When viewing "Properties", there's 2 partitions, 138GB+136GB. So over 14 percent is lost in formatting (or ??). This is not space consumed by existing files, it's total available on each partition. The average format overhead runs ~ 7 percent; this machine is worse than double that. Has "Altec Lansing" speakers; but audio is terrible. No low frequency at all, and max volume is nowhere near any other laptops we have (Acer, Dell, HP, Toshiba, etc). This computer is a HUGE disappointment. And it is SLOW, SLOW, SLOW!!!
Pros: PROS: Good quality device, well built, not flimsy nor "cheap" in construction. The product arrived very well packed, and included a brief instruction pamphlet and a card with contact information for support from the manufacturer. The device performs as claimed, and does not even get hot when fully loaded. Others I've tried made me worry due to their thermal increase under load. I would recommend this product to anybody seeking a multiport charger.
Cons: CONS: Took a long time to arrive; 19 days. This was not the fault of the manufacturer, but the USPS and/or Newegg. USPS tracking showed only "Label created" until the day after delivery. Other items shipped via USPS generally have been taking a week or less; no idea why this one took so long. However, that's not a reflection upon the product quality.
Overall Review: SUMMARY: Excellent quality product. I would recommend this product to anybody seeking a multiport charger.
