Cons: none

Other Thoughts: They're cheap and they insert the proper voltage on the proper wires... what more do you want?

4 out of 5 eggsGood PoE injector for low price

Pros: Cheap and uses the standard for PoE. Worked well over our 220+ foot run as well. (It powers a bridging Netgear access point that has a high-gain [12 dB] antenna on it.) Also has a very easy-to-see red light for indication purposes.

Cons: There are no holes on the back for mounting. Kind of a shock for me, as I needed to mount it to a board for the project I'm using it in, but not a big deal; A bit of masking tape did the trick for now. Metal braces are going to be the permanent solution.

Other Thoughts: Good product, and haven't noticed any reasons not to get it again. (Actually will be using it again for when we put in the 4th bridged access point. This one will only need to do a 30 foot run though. :-P)

4 out of 5 eggsWorks with Linksys SPA942 IP Phone

Pros: Works with my Linksys SPA942 IP desk phone. Low cost.

Cons: Does not appear to sense if device is connected. I tested with a multitester and found it was putting out 48v at all times across pins 4/5 and 7/8. Be careful what you plug into these.
Large power brick... blocks outlets.

Other Thoughts: These are the same midspan injectors that are included with the EOC-3220 access points.
