Great customer service. Collar arrived quickly with no hidden charges. Best price I could find anywhere. I have used e collars for many years now, I still have my Dogrta & Tri Tronics as back ups but I don''t see myself returning to those brands unless they change the feature significantly. A great polishing tool or even a good beginners tool with great features, lots of YouTube videos on how to change the features on the collar unless you just want to use it standard. I recommend this to everyone who asks.
