Not working, it trips.

When using this my outlet always trips and can't use it.
This is not working as expected.

I bought one and loved it so much I bought another one.  The motor on that one stopped completely.  Someone said to take it apart and it may work so I'll try that before I donate it.

Just got the new unit installed and the thing trips the GFCI. Not even one use. Removed the rod and the GFCI does not trip. This is not only a bad item but potentially fatal if you don't have a GFCI on your unit.

It seemed to work well until it didn't. I called the company to see if they had any insight to getting it working again and their response was: buy a new one, buy a refurbished one for almost price of a new one, or pay to send it to us to fix which is $25 labor minimum +parts. I get it, we live in America where everything is cheap and isn't warrantied for more than a year. However, I would expect a little more than this. Look for another brand.

I bought 2 of these, and one has completely stopped working!  I need to , hopefully, return it and get a different one or a refund.

Despite charging it fully and many attempts, the car will not jump at all. Instructions say to press a button and listen for a winding up noise, but no noise ever starts. Really disappointed with the quality control on this item. Good thing I bought it through Amazon. They're a great company and addressed my complaint quickly.

didn't work, maybe it was just defective, never returned it because it was so cheap, easiler to buy another one.

The cable was faulty on mine. It wasn't under any type of stress at all, it wasn't even under its own weight and it failed. I can't recommend anything like that.

I bought this, it was cheap enough that I didn't feel like sending it back.  Do not buy this, it will not work.

Bought this unit in May of 2016 after reading reviews on Amazon, it has not worked properly since the day we took it out of the box. It will trip after 5 minutes. We have tried running it on its own circuit, still trips. We have tried running it on a generator circuit that our 2 high output sump pumps run on and it trips, we have tried running it in the pool house on its own circuit, it trips. I have brought it to work and plugged it into the same circuit we use for our 15,000 BTU AC and you guessed it...It trips. Why have I waited so long to write this review you might ask, only answer I have is that I am lazy. I am guessing I just bought a faulty unit, based on that I can't really give an honest review aside from my own experience. Currently in the market for a new unit - Does anyone have any recommendations?

My board does not work. It is behaving just like two previous reviewers described. The device seems to latch-up and draw excessive current and get very, very hot. It does not pass data in either direction. I would like a replacement or a refund for this item.

Does not work, better off getting something more reliable

After setting it up per the instructions, and flying it around in my house for about 3 batteries worth of use to get the hang of it, I waited for 4-5 days for calm weather.

You can imagine my surprise when it stopped responding to the controller (of course it was full throttle) flew up high enough into the sky to disappear, and is now gone. Total mechanical failure of some sort, and the seller says there is "not under warranty for a fly-away item" and if it was defective "that it would not fly at all" I get that this is only a $30 drone, but I did everything correctly, and it failed.

I was offered a paltry $3 discount on a replacement.

Guess what I'm not doing?

Very cool when it worked, the problem is when it worked.  It would not stay spinning to long before it made contact to the top or the bottom.

We bought this for a long trip and it stopped working within the first 100 miles.  We have tried it several times since and it works at random times.  More often than not it just doesn't work.

Best I can tell this does not work.  Placed on the chain stay of my bicycle they cannot get any closer to the ground.  I even lay the bike down close to the ground at various points in and around the embedded sensor wire circle or square.  It still does not work.

Cool idea.  If it worked.  I cannot recommend this product.

There seems to be a relatively consistent problem with the circuit board in this thing frying itself. My daughter's stopped working after about 4 months and it's clearly because the board overheated. Spend a little more money and get something higher quality.
