The seller was good. the collar arrived faster then expected so that was great. The only issues I have with the product is the instructions that came with it. they are really weak and it is going to take some playing with the collar to figure it out.
IE:Iit does not tell you that when you put the batteries in the collar it can take a long time (15 min) before the collar is ready.
also you get a extra LED light in there, which is nice, but it does not tell you what it is for, so you sit there trying to figure out what to do with it. Thank god I know what an LED looks like other wise I would have no idea what to.
