Review on igingko Dog Training Collar: 1000ft Range, No Harm Shock with Remote - Waterproof, Rechargeable for 2 Dogs, Orange by Jeff Young

We bought this for our two dogs and found it very easy to use. A remote control works well and you can easily switch between the dogs. In most cases the beep is a deterrent, in rare cases we use vibrations with an adjustable level. Great value for money. We haven't checked whether they're waterproof, but that was an advantage for us. The reason for 4 stars instead of 5 is that the transmitters were not attached to collars and did not have open slots to attach them. My husband had to remove the buckles (ripping the stitching) to put them on.
