Pros: Nice Metal Case
Small Size Device
Stays pretty cool
No Noise/ No Fan
Low power consumption
Great LED indicators for different speed connections
Reasonable Price for the product
Cons: My only complaint with these types of switches is that all of the connections are on the front of the device and of course the power plug is on the back of the device.
It would be nice to have the power and all ports on the back of the device with LED's attached to each port as well as putting a second set of LED's on the front of the device for easy "at a glance" views of each port.
If you mount these on the wall or place them on a desk top, it is difficult to make them look good and still remain functional due to having to route cables and power connections to opposite sides of the device.
If you are just putting it on the floor, no big deal. But, if you are trying to mount it on the wall or place it on a Desktop, it looks very busy and disorganized due to required cable routing. Of course, the ideal the orientation of the unit gives you full access and view of the activity/signal LED's.
Other Thoughts: I purchased 2 of these to use with my home network to stream video and data between the TV area and my Office / Modem-Router devices. They are 70 feet walking distance from each other.
At the TV location, I have connected a HAVA PCTV To-Go Device (Video Streamer like a Sling Box), a DirecTV HD DVR Receiver, a TP-Link WR-1043ND Wireless Router that I'm using strictly as a Remote Access Point, a Seagate FreeAgent Theatre+ HD Media Player , and a Buffalo NAS device holding all of my movies, and a Wireless Wii Game Machine.
In my office, I have connected my Motorola SurfBoard SB-6141 Cable Modem to a TP-Link WDR-4300 Wireless Dual Band Router , and then connected the Router to supply signal to each of the 2 New Switches Plus an old 8 port switch and an Obihai 100 VoIP device.
To the New Office Switch, I have connected 2 Desktop hard wired PC's, a Buffalo NAS Backup device, a Laptop PC as well as a VoIP NetTalk Device. I still have a couple of open ports. So far, everything seems to work just fine for streaming HD videos from Netflix as well as movies from my NAS/Seagate Theatre+ Device, as well as streaming video to remote devices and internal devices using the HAVA PCTV To-Go Device. I have done all of this while running Backups concurrently to both Buffalo NAS devices without any issues.
Throughput seems to be very good and I highly recommend these devices.
Pros: Worked OK in an HP Pavilion a347x.
Priced well for the memory sticks
Cons: DID NOT WORK in the machine I purchased them for which was an HP Pavilion a1267c machine that is suppose to be able to handle up to 4GB RAM.
This machine has 4 slots. I could not get either stick to work by themselves or in conjunction with any other memory stick including the existing working RAM in this PC. When I put the original memory back in the PC, it worked just fine again, so I added 2 OTHER memory sticks I had laying around to this machine to bring memory up to 1.75GB and I'm working with that.
I'm really disappointed as I was hoping to wind up with a full 3GB of RAM consisting of existing 512, 512, then add the new 1GB + 1GB for a total of 3GB. Unfortunately that didn't work.
I brought the memory home and plugged it into another HP a347x machine and they appear to work just fine.
Other Thoughts: This is the first time I have had compatibility issues with matching RAM to a PC. Evidently there is some type of timing issue with this RAM as the PC would only beep at power up with a single stick or multiple sticks inserted in every possible configuration allowed by the MB Manufacturer.READ FULL REVIEW
This review is from: Obihai OBI100 VoIP Telephone Adapter with SIP
Pros: Easy Setup, Great Google Voice integration, Amazing Voice Sound Quality and Clarity, Great Voice Volume on both caller and receiver's end of conversations, No Monthly Fees for GV phone service, Free Obi to Obi Direct phone calls anywhere in the world, FULL DUPLEX audio conversations just like a real landline phone, Fax Compatible, supports up to 2 SIP Providers at the same time, 98 number Speed Dialing, Caller Number ID and Voice Mail Alerts on your phone display (if your phone is capable of displaying them. Voice Mail Audio Alert as well via "Stutter" Dial Tone when getting ready to make a call, and the list goes on and on
Cons: NO 911 or E911 Service, BUT, you can add it via a SIP Provider for about a dollar per month or so if you must have it for some reason. Otherwise, just use your Cell Phone for 911 Needs. Any old Cell phone (active or inactive) can always dial 911 in USA.
Other Thoughts: Just some background, I have a Magic Jack (older one that requires a PC to use it) and a NetTalk DUO that connects directly to my Router. I have used them both for a couple of years now, and the NetTalk Duo works extremely well compared to the old Magic Jack. I have pretty much disconnected the MagicJack device and have been using the NetTalk Duo as a 2nd line and Fax Line, but those I call from the NetTalk Duo say that my audio is low on their end. On my end, I can usually hear them just fine. The NetTalk is costing about $30 per which is not too bad, but I wanted to find a way to have good quality calling for free if possible and eliminate my $30 per month Ma-Bell bill as well as the $30 per year NetTalk Bill.
Some research on my part uncovered the Obihai Company and the Obi100 VOIP unit. With all of the great reviews, how could I go wrong! I purchased 3 of these with the intention of equipping my home, my son in the military and my mother with free calling between these units using the ObiTalk Network, as well as anywhere in the USA and Canada via Google Voice Network(still free for the rest of 2013 and hopefully beyond)
Setup of the Obi100 was a breeze, and I linked it to Google Voice which also has outstanding Call Routing, Voice Mail, Notification, Transcription and other cool features/services all for free (at least through 2013), so that is hard to beat.
Best of all, the Audio and Call Quality are TRULY AMAZING!!! Believe it or not, they are much better than my expensive Ma-Bell landline, and the audio volume is loud and clear as well as being Full Duplex just like a traditional landline phone. I found that the NetTalk and Magicjack behaved more like a speaker phone or walkie-talkie allowing audio to travel only in one direction at a time which is very hard to get used to since you tend to cut off each others sentences when holding a conversation with these other devices.
The Obi100 does not suffer from these problems at all, and there appears to be virtually no audio delay. Also, since my son is in the service, it's very convenient for him to take his Obi100 with him and connect it to the internet wherever he is in the world, and he can enjoy instant phone service and we can directly dial each other's Obi Units and talk for FREE on the ObiTalk Network at any time.
I'm in the process of porting my home phone number to the Obi Google Voice Network (via a temporary porting to an old TracFone first as Google Voice will only allow you to port Mobile Number into Google Voice a this time)
There is a great Obi Forum, tons of youtube.com videos on these devices and how to use them with a variety of SIP VOIP Providers as well as free Desktop, iPhone and Android Phone Applications that all integrate with the Obi products.
Purchasing and Installing this Obi100 Device was one of the Best Decisions I have made so far in 2013!!
