Most work great, but some are flimsy

I've bought 16 of these before, but 2 of them had their locking mechanisms break off after the 1st use.  They just snapped off.  They were 5 stars up until this last purchase.

some of these worked great and charged great and some of them did not. But for the price I would highly recomend them

Only 3 out of 10 of these worked for me which was disappointing, but the ones that do work are fine.

Out of 6 one didn't work but the ones that did work are fine, great price too

The ones that worked work well enough, but one of the three came with a battery compartment door that won't latch securely.

Its a great concept and they work well but are a little on the flimsy side.  As long as you are not looking for a long term solution these will work well for a while before you need to replace them.

good price, poor quality - some of them do not even work.

These are great--when they work.  Out of the 4 I received, one of them wouldn't ping a signal to pair it with my phone.  The others worked fine Would have given 4 stars if they all would have worked.

Bought more than one for my family but a few of them were a bit shaky and not as sturdy.

The ones that work in the pack work great but about 25% of what got shipped to me don't work or has a short.

They work well, but are a little filmsy. Have to be careful with them.

Bought these connectors to setup a Cisco lab for my studies.  I just needed the cables to connect and be somewhat reliable and on the cheap so I gave these a try.  I built about 12 cables and had only one with a bad connection which was probably due to my crimping skills.  These work as advertised, but like others have said they do not click/secure into the port easily.

**If you're dead set on getting them to latch in and be secure, grab the locking tab and hold it up (instead of holding it down to release it, use your thumb to hold it up) and then press the connector into the port.  You may have to wiggle it a bit, but it'll click.**

I gave it 3 stars because they work, but they don't secure very easily but they are dirt cheap - you get what you pay for.  If you're looking for something a little more permanent, I would opt to for connectors that are tad bit more expensive, like the Belkin connectors, which are way better quality than these.

They are a little flimsy. You need to be careful installing them. Besides that they work great so far.

One didn't work out of the box, rest have worked great for some time now

One light came in broken.  The ones that work are excellent.

These work well if they don't break. About one out of five snaps in half when you try to open or close

I've been using these for about a month and a half now and they worked great the first couple of weeks. Now some will work, some won't and they aren't as super bright as before.
