The fob was very easy to setup and seems to be doing great a month after purchase.  You do have to push down with a little extra force to engage the locking contacts on the fob sometimes but all in all this is a five star purchase.

Not a picky person so if it installs like it's supposed and operates like it is supposed to, them I'm satisfied. 5 stars!

It works better than expected and is VERY EASY TO OPERATE (unlike a most of the competition).  The remote control off/on function of the collars was a pleasant surprise.  The collar receivers are smaller than others I've used but seem to work quite well with very good range.
Both my dogs have thick neck fur and I will not shave them as suggested in the instruction manual (which is written in real English). Unfortunately the receivers only come with one length (medium) of probe.  I did not think they would reach the dog's skin, but they do and seem to work well  (although my dogs never need the shock treatment).  One hit of the tone or vibrate function and I immediately have their total attention.
I am mildly concerned about the somewhat tiny and cheap "dog selector switch" on the side of the transmitter and hope it will hold up over the long term.  Note that it is MUCH EASIER to operate than other brands many buttons and you don't have to search for some tiny indicator on the display and guess which dog you have selected. You can easily and quickly feel the switch with your fingers.
I only have two suggestion to the manufacturer for product improvement.  (1) is to get rid of the plastic collar straps & buckles and change to a more flexible woven cloth strap with a quick release snap;  (2) install a felt washer behind the knob to make it considerable harder to accidentally bump and turn to a unexpected position.  It turns too easy now but is very simple to use.
NOTE TO BUYER:  IF you are looking for a SIMPLE SYSTEM to operate with great range, it just does not get any simpler that this.  Believe me, I've tried several others and this is by far my favorite.

Well built, easy operation. The directions must have been written by someone who knows zero English and less about the product! I hope they didn't pay much for the effort. My order was sent without the pole. Quickly corrected and reshipped.

Very smooth operation and quick inflation.  As others said, it is a bit of a challenge to stuff everything back into the case, but it can be done.

Unit functions flawlessly underwater. I swim an hour at a time with nonstop music.
Programs easily and operation is simple.
If any, only small drawback is quality of earphones/buds. Sound is average at best and you have to really manipulate properly to make sure sound is constant and no water gets in between earbud and ear canal. But worth the hassle.
