Patriot PS5 Solar Energizer - 0.04 Joule Solar Powered Outdoor Charger for Camping, Hiking & Emergency Power Supply

The jury is still out on this unit. When I first unpacked it and set it up per the instructions, it didn't work. The instructions directed connecting the leads to the battery. In my unit the battery was already connected which was suspicious. I put the unit in full sun for seven days (instructions called for five days), switched off per the instruction. When I hooked it up and turned it on, it didn't work. I tested the little lead acid battery and found that it was well below the specified voltage. I reported it to Amazon and, since it was non-returnable, they promptly refunded my money.. I decided that since it was basically a throwaway piece, I would experiment with it. I cleaned the battery contacts carefully then put it back in the sun for several days. When I hooked it up and turned it in, it worked for a few hours. So, I followed the charge instructions and hooked it up again. For awhile it would not operate all night, but after a few days of turning it off during the day and leaving it on at night, it was still working in the morning.Since then I have generally left it on and it seems to be working as described. If I don't have any more problems for a while, I'll edit this review to add one or two stars as it is a nice compact unit. with good instructions (and it's $25 less than the same unit in a local farm store).After succeeding in getting the unit's battery properly charged I found that it has worked satisfactorily all summer. It is not a strong shock and it's hard to tell whether it's working or not as it doesn't make any sound and the pulse indicator light is very hard to see. However, I found that it does shock any grounded body and it will burn grass or weeds that happen to grow against the wire. So, I have added two stars to my review.
