Pros: I bought similar products in the past. This one actually worked. Configuration is easy once you figure out the default SSID password (11111111). Software for OSX, iOS, Windows and Android exists (to connect to the setup) and to view drive. Shows as device in Finder. Streaming videos to phones, tablets and computers works well. It integrates in your (home) network and does not disrupt your access to the internet. Charging from the battery is a bonus.

Cons: I wish it had an ethernet port. That way it could be used as universal travel router as well. If it also had a DNLA and may be an ITunes server it would be perfect. Yet, that would probably increase the price and decrease the battery time.

Overall Review: Its the perfect portable way to increase your disk space especially for videos and other large files. I tried it with a 64GB SD card and a USB drive. I also tried it with two USB connected mechanical drives. One was OK and the other did not get enough power.

Pros: Speed seems as advertised

Cons: Card has been advertised and purchased as 16GB SDHC card. Card has been delivered as 8GB SDHC card. On first attempt of RMA the RiDATA website "asked" for return shipping payment. I then posted another "review". RiDATA responed via email and offered a free return shipment. They stated they would issue a UPS return whatsoever. I received the UPS return whatsoever and went to the UPS website. It turns out that the return shipment (UPS) was not prepaid; UPS wanted me to pay for the shipmemt.

Overall Review: Mistakes can happen. We are speaking about the difference between a 8GB and a 16GB SDHC card - no big deal. Yet, RiDATA seems to be as incompetent and ignorant as any company can be. May be their mistake is honest but their repeated failure to straighten out things is more than bothersome. Again: Avoid this company - at least for this type of SD cards.

Pros: Cheap for the capacity. While extremely slow it otherwise works - mostly...

Cons: Horribly slow (at least when connected to USB2). This is the slowest USB stick that I ever purchased in the last 4 years.

Pros: Price! This thing is great when using it with motion detector app to send emails with photos taken from the device as attachments. Any surveillance system would be much more expensive. Or use it as VOIP phone.

Cons: Cheap built, cheap everything.

Overall Review: 5 stars because of price.

Pros: I don't own the Nokia E7 but I have a Nokia N8 and a Nokia 808. The N8 originally ran Symbian ^3 and was subsequently updated to first Anna and then Belle while the 808 came with Belle out of the box. The E7 is similar to the N8 except that the N8 has no physical keyboard and a much better camera and a microSD slot. All these phones are pentaband GSM phones meaning they will work with nearly all GSM networks in the world including AT&T and T-Mobile. Nokia's GPS application is outstanding (with free maps world wide). I would recommend these phones for use with a prepaid plan and for international travel (internationally the phone can be used as a hot-spot with a free app.

Cons: If you need more than standard apps (like Skype) this phone is not for you. Symbian Belle is a fine operating system but ... No LTE. If you want to use the phone just in the US then you will probably be better off buying an unlocked, more recent Android, Windows or iOS phone.

Overall Review: If you want to get the best camera currently available then go for the Nokia PureView 808 instead. If you just want a simple, cheap unlocked GSM phone for use within the US and if you do not need GPS then avoid Nokia. If you travel internationally or if you need a cheap secondary phone and if you don't mind the lack of LTE then the E7 might be a great option.

Pros: See prior review

Cons: The only way to power the device (and to charge the batteries) is via micro USB input - and this port is far to flimsy. It broke within 2 months and the device is now rendered useless.
