If you don't sow 'em, they won't work

My family has not used them for the cats yet. And they were Christmas presents! The cats are still eating the houseplants. I thought this would keep them away.

They failed to operate.  Tested them in a known good receptical which worked with an incandecent bulb.  Specific reason unknown.

These are a little unpredictable, they don't always work.  So, if you want them to go on vacation, you may come home to dead plants.  :(

They are difficult to install as they do not work with the splicers they are shown with. You need to strip the wires and use waterproof wire nuts. They worked great during the summer and fall. We live in Ohio where there is snow. When we turned on in the spring 5 of 18 do not work. Appears they are waterlogged. The company does not tell you they can be used outside. DO NOT BUY if using outside where they will get wet. I wasted a lot of time and money.

Bought 8 of these lights less than two weeks later only 4 are working I took up two apart recharge the batteries on a battery charger and they still don't work. Others have said comments about the quality of these lights and I now believe them they don't work. And yes they are getting plenty of sunlight to charge the ones that are out are within 3 feet of ones that work on the same wall.

I bought these directly from Jim's farm. And I bought 2 orders (4000 worms) Plus I bought an additional 100 European because they were just $10 more. They were definitely sickly (not moving and very tiny) when I got them.  Most were juniors or smaller, so it will delay my business by 4 months. It took them 16 days to deliver.  WTF?  Over 2 weeks?  I was so mad.  I took off days at work to be home when they arrived. Try telling your boss, your hair stylist and doctor you need to cancel or not go to work because your worms will be arriving... and cancel again or not show up to work a few more times because they still didn't show up. Try waiting 2-Day Priority Mail (and paying for it) and waiting 16 days.  I was so mad.  To say the least.  I contacted them numerous times and they (lied) saying they were on their way when in fact they weren't.

I've now had them for 2 weeks and they are looking great.  They eat like crazy.  And I smile every time I look at them.  Most posters spoke about weight loss or a lot less worms than promised.  I didn't count or weigh, so I can't give an opinion on that.  I didn't feel they should be out of bedding any longer so I put them in the worm farm right away -- I think they were traumatized enough so having them in light for a few hours to count was out of the question!

I have searched for other worm breeders to buy more, but most of them are drop shippers or sent from China.

Overall, even though they didn't ship out for 2 weeks, I got them and they seem to be thriving very nicely.  Now that I know they ship only on Mondays and it takes 4 days when shipped, I will buy again from them since they arrived alive and they are the worms I wanted and grown in the US.

they do their job.  the metal they mount to will fail before these do.

They worked for a week or so. After that the deer had no problems feeding in the field with the eyes on

Please, be smart.  See all the other reviews by people saying that they were unable to mount them up?  Well don't be a dummy like me.  I thought I would be able to figure out a way (afro-engineer) to make them work but NOOOOO.  You will most certainly NOT be able to use these.  I'm not kidding.  You are throwing your money away on these if you buy them.

Don't be cheap, buy something that works - 6/24 Did not work - 2 others were dim - Enjoy getting punched in the neck by 1st graders? Buy these and hope the strong kids don't get the bad ones.

Purchased these in March, used them once a week while doing yard work, it's now June and they no longer work.
They worked great while they worked, unfortunately they do not seem to be built to last.  According to Amazon's return policy they are not eligible to be returned.  I would not recommend these.

EDIT 07/02/2016: Was contacted by TaoTronics Support Team within 24 hours of posting my original one star rating of this product, informing me that they were sending me a new set free of charge.  Excellent customer service, I've re-rated this to three stars (up from the original one star) based on their customer service and will return to edit again aft I use the new set for a couple of months, hopefully the first set was a lemon..

They work fine, don't hang next to any electric string lights though, they won't turn on till those turn off.

I followed the directions, charged them to full when I got them, and used them twice with my phone for a hour long workouts. They worked great when they worked. But, now they won't turn on. I've tried charging them and the light turns on when I do that, but when I go to use them I press the power button and nothing happens.

Great lights if they work. Love the flashing mode, but one of the sets only worked one day and died. So far, the other set is still going strong (knock on wood). Need a replacement for the broken one.
After opening the solar battery pack, I discovered that the battery was not all the way in it's connection. I thought I solved the problem, but after letting it fully charge for a day, they still didn't work. So, then we went out and purchased some pre-charged batteries of the same type. They only worked until the pre-charge ran out; which means the battery is not getting charged by the sun at all. This strand of lights is defective.
Owner of store, please contact me for replacement lights.

My gardens sit in a rest area of what seems to be a deer superhighway.  Last year they decimated my carrots, pumpkins and peas.  This year they started mowing down everything as soon as it emerged from the soil.  My neighbor told me about the scarecrow sprinkler and since everything else I tried had failed, I figured I would give them a try.  They worked excellent at first but two problems arose.  First the 9v batteries ran dry very quickly, leading to no activation and the deer mowed down my peas again.  Pay attention: when the sprinkler activates but only for a second or two unlike the normal 4-5 second burst, the battery is almost dead. Second, ensure you have a good seal where the hose connects to the sprinkler and good hoses.  I found it fairly difficult to get enough teflon tape on the male hose fitting to effectively stop the leaking.  Sitting in the sun, under constant pressure, old hoses will fail.  I left for a weekend and got back to a busted hose.  Got my water bill today and I burned through 21,500 gallons of water for the month of July 2013 instead of the 1,000-2,000 gallons I normally use.  I used my well to water the garden and not the municipal water supply. Oh and one more thing, pay attention to the wind.  Leaves blowing in the wind tend to set off the sprinklers.  If it is supposed to be windy, turn down the sensitivity.

The Scarecrow sprinkler keeps the deer away (when they are working correctly) and that is a fact.

An improvements could be made though.  Metal female hose connection.

These things do not work. We were just a couple late on returning them and the seller wouldn't take them back. I will never use them again, avoid them, they are bad news.

I guess they work.  Who knows?  There is no test to prove they don't work.  It's not like u'r paper shredder will quit after 30 days from the last time u used one of the sheets.
