Remote Training Collars

I have just recently seen this because a few friends of mines are dog lovers, I mean the dogs have their own room and everything! So we got to talking about what they need and this topic came up about dogtra iq. I thought this was a great idea because I read all the features and i cant see how any small dog owner would NOT want want to get this, its genius. It has a 400 yard range, water-proof and the receiver has an off and on switch...and many more. I think I know what to get my dog lovers friends for the holidays, its a little pricey but well worth it.
