Terrible. Do not waste $100 on this piece of junk. Did not work. The only thing it did do was to charge the battery. The pump would never activate. Left it on a table outside in the sun for 3 days. It would not even transfer a single drop of water from the rain barrel to a bowl on top of it. There is no way to turn it on manually which is a bad feature. Needed to wait days just to watch it do nothing. The light indicates the battery is fully charged. Thats all it does. Ordered a replacement. If that does not work I'm building my own with an arduino. I'll post the instructions here so others can avoid this. Great idea. Too bad it's total garbage.

I'm not understanding the negative reviews at all. I bought this 2 years ago and the thing is amazing. I have a small garden (20 plants) and it has been more productive than ever before! In fact, I'm buying a 2nd one this Spring to irrigate some hanging baskets and other flowers around the patio. From time to time you might run into minor issues, but if you read the website and other troubleshooting tips they are easily fixed. For example, my pump wouldn't kick on after being put away for the winter (kept inside). I read some reviews and used the included syringe and sprayed some water into the inlet and poof, it worked like a charm again. I would highly recommend this product if you want to get the most out of your garden!

Never worked.

I installed this unit as directed ...it worked somewhat for a week then stopped. no signs of life and I'm stumped as to who to turn to for help.
this was not cheap so beware.

Like some other reviews, the pump on the unit quit working two-three weeks into use. I emailed the company (in the UK) and a replacement pump was sent with no trouble what-so-ever. We'll have to see the longevity on the replacement pump to see but, the product works as advertised and considering that fact, I would recommend.
