Verily lightly used, I used it only a few times and it worked just fine! I just don't need it anymore is the only reason I'm selling it! Very good brand and both the remote and the collar are rechargeable and the batteries last a long time! Look up reviews on cabelas website if you want but it's a really good training collar. It has 15 different shock levels to choose from including just a beep level wth no shock. It comes with 2 different sizes of contact points. Water proof. 1/4 mile range. $160 new from store. Call or text with questions! 316-842-1004
