Pros: -Removable controller. If your controller dies. You can remove the controller and you have a SATA power + data connector. -USB 2.0 & USB 3.0

Cons: -A bit bulky -Plastic material=thermal insulation= not good.

Overall Review: - People who complain about proprietary connector... it's not. It's called SATA. Inside EVERY computer theres SATA. -Unreliable Cable... Some applications don't send the message to keep-alive the drive. That's why your files are freezing. Do you homework and stop being lazy.

Pros: Good quality

Cons: -MAJOR, no POE. You need a POE splitter 40$

Overall Review: These phones are usually deployed as quick access phones. In a shop, at an entrance ...etc. Having power in those places is usually impossible. It's cheaper to buy a standard analog phone 20$ + a SPA2212 (PAPT2) at 40$ this phone is 60$ + a 40$ adapter...makes no sense.
