Feliway wipe applied inside the carrier worked for about nineteen minutes of the car ride home from the vet. She was characteristically quiet and personable. Then, while we stopped at our mailbox on the way up the driveway, the clock ran out when she meowed loudly and pooped a big one (as usual.)

Too bad.

I felt as though it did not heat up hot enough. I even let it warm up for more than 20 minutes (under supervision).

It works best for the RZR its installed in however the door to it was broken off just twenty minutes into maiden trip, That wasn't the fault of the design however.

Worked good for like 20 minutes, the longer I used it, the less amps it made, when you lift the pedal, takes like 5 seconds for arc to completely stop, I have Lotos plasma cutter and it works great, no problems with that, this machine, no so good. At first seen a lot of good reviews, now nothing but negative ones, but a Miller or lincoln

I cranked mine for one and a half minutes and the radio lasted 6 minutes. Possibly somebody on the assembly line is inserting junk batteries--this couldn't be the way it was intended to work.

After I replaced the batteries it never really worked again. I could turn the top a little this way or that and get it working but then it might cut out mid ride. Eh

It does not allow the scooter to go fast enough. But, nonetheless, the work. And they last all day.

GREAT for a few rides. I purchased three and non of them lasted more than two weeks. Non of them would recharge and one of the connectors worked loose on one of them. BUT While they were working they worked great!

Mine worked for about 4 days  Light clicked off while the arm was up and that was all there was.  Plugged heat gun in same outlet and it worked fine so not electric issue or blown braker.  Just really cheap item.  For 20 bucks I do expect more then 4 days of use.

After charging the battery. Went riding and the battery lasted 20 minutes. I had bought four of these and have only use the one so far the jury is still out on the other three. Need to contact Amazon or the seller to get a replacement.
