Review: Great charger battery has never run down easy to move and set up solar power very hight output and it a nice small easy to use Works perfect
Review: Plug and play. Awesome output even on fence that's old and likely has a lot of resistance. Keeps the sassy pony and his taller friends in no problem as well as keeping the overzealous dog out as well. Sits right on top of a T-post in a pre-fabricated slot in the bottom for easy attachment. Not nails, no intense installation. Plus the T-post is a handy, instant ground rod to boot. So the convenience is great. The auto/night feature is awesome too. Very happy with this set up so far. Have used since spring (about 4 months) and am satisfied enough to where I ordered another one.

*by S***N on 10 January 2026*

Last summer the deer ate nearly everything in our garden. This summer we upgraded - the deer got NOTHING! It's easy to install, charges great, the batter life is superb, and the price is so much better than one with a separate solar panel. I have recommended this product to several friends who have purchased one. From experience I can tell you the shock is enough to ensure you don't want to touch the wire a second time.
