Worked but not really.

Bluetooth component worked flawlessly.  Easy to setup, easy to control.  FM transmitter component didn't work at all.  Live in Chicagoland which is notorious for "crowded" FM signals, but even when literally hanging the unit from the antenna, got little-to-no sound.  Bad or refurbished unit?  Disappointed either way, returned.

Wasn't that impressed. Doesn't seem to charge my phone and tablet any faster than those plugs I have at half the power. But it does work.

I had marginal success with this; even in combination with the Sentry Calming Collar.  I used it for a 22 hour air trip, so that might have made a difference in its level of success.

Did not work universally as advertised. Had to return.

Works in principle, but not even close to the real thing.

Might have worked for some but I couldn't get a repeatable reading out of it.

Works most of the time and certainly helps, but it's not a perfect solution by any stretch. Still, not a complete waste of time or money either.

This product didn't preform the task it claims to.

The product worked as advertised. It just wasn't as much of a laptop substitute as I was hoping.

This worked somewhat. Effects didn't last very long. I suppose in a pinch it is ok but we have moved on to the bigger name brands they cost more but they really work well so I won't be going back to this brand

I'm not sure what to say about these because they worked.  The problems I found with them are that they are difficult to crimp because of that hard plastic housing and didn't seem to hold really tight on 18 gauge wire.  I had to use channel lock pliers to get them snugly crimped and I used some heat shrink tubing to make a little more secure.  I did find that the female ends have that red housing extending out past the connector inside.  If you get that housing a little warm around the open end, it shrinks too.  That makes it impossible to plug the male ends into.  That's why I didn't give it five stars, I had to redo several of them, but there's plenty left over, so it's not a big deal.  Aside from that, they hold very tight when connected and they work well.

When it worked, it did what it supposed to do. But after a few months of light use (less than twice per week), it crapped out on me.

Tried to use these for removal of the snap ring on a GM NP246 transfer case (that had the infamous pump-rub failure). These didn't quite do the trick. I added tape and plastic tubing to the ends to try get it stretch a little more, but didn't work. In the end I used these with a flat heat screwdriver wedged in between and managed, but these are not the tool for this job.

At first this thing did not seem to work at all. As the mosquito bites were multiplying, the mosquitoes in the trap were not. After a while there were a few of the little ******** dead in the trap. I guess it was better than nothing, but not as effective as I had hoped.
