Worked great the first time I used but downhill from there...

worked great for like a day but then the "locking" mechanism stopped working so the dispensing holes slide open wide easily and dump the treats out too quickly.

These worked great the first time but then I went to go use them on a another batch and they were leaking at the scenes where the plastic joins.

Worked great the first time but the last two times  i got stuck with huge bubbles. The last two were a wast of money..

i used this tool twice first time it worked great the second time however was a completely different story the socket keep sliping in the hex nut i was attempting to remove i lloked at the socket and noticed several pins where broke and wouldn't return to there position so i stuck a screw driver in the other side to attemp to force them back in place it worked tryed it again same story but this time several more pins where stuck so i just threw the piece of junk away and cut my losses i hope eventually a universal socket would come along and fix that issue because it would be nice to have one socket to do it all

I got this to recharge the batteries for my cell phone and gps tracker while on a ten day backpack trip on the A/T. According to the specs, it should re-charge four to five times. Did fine the first time. The next night I used it again and it drained down to one charge remaining. And that charge was unable to recharge the phone. That all being said, the next time I tried it it did better. Turning the phone off while charging worked much better.

Worked great the first time I used it. I followed the instructions on breaking it in. The next time I fried steak in it, the steak stuck to the bottom of the pan. Since then I haven't been able to get it clean without a lot of hard scrubbing. I am very disappointed.

The 1st time I used it, it worked perfectly. Recently canning the same thing the reuseable pressure valve did not seal and never built up pressure. If Mirro or Amazon has a solution I would give a higher rating. 3 times using is NOT acceptable with 2 out of 3 not correct

This item worked GREAT the first time I used it. However every time since it's gotten progressively worse. The last time I used it the steamer spit boiling water not only all over the blouse I was steaming, but also all over my hand, even though I made sure not to overfill it. I tried tilting it at different angles and it made no difference. I've given up using it because it ruins my clothes and I don't feel like burning myself again. I've used it about 5 times total.

This worked great the first time I used it. The second time I placed it in the pool to run overnight. When I went out the next day I had water pouring out of the bottom of my pool. It had gotten stuck on my steps and tore a two to three inch hole in the bottom of my liner. This vacuum has decent reviews, and for the price I thought it was worth a shot. After this happened, I read over some of the negative reviews and found a few other users had experienced the same problem. Amazon refunded my money, but now I have to spend several hundred dollars to replace my liner. Please do your research before buying this.

i was really excited about this product, it worked great the first time, but then one of the legs chipped after about 1 week of use. Very unfortunate for me, i would love to recommend this product had it not broke soooooo easily!

Worked great for me one time, then the next time I went to use it the heating element refused to warm up.  The LED's are a handy addition though.

Loved the product the first and second time I used it, but then one of the legs screws broke after the second use.  For the money I would have figured I could have gotten a good year or two out of it ... if not longer.  Very sad.

Worked great the first time I used it. Now it won't turn on at all - just makes clicking noises. Save your money and buy a decent bench grinder that's made to work properlyl.

I worked well the first time, but when I wanted to use it a few days later, the liquid had hardened inside the nozzle.
So, great for a one time use, but I need to try to unclog the nozzle to use it again. I hope it doesn't clog every time....

I was excited to order this. It came to the house and was great the first time using it. I went to use it the next clean up and the bottom tray part where you scope the waste into is very flimsy. It won't stay down to allow you to scope the waste into it. Very disappointed.

Worked great the first time out of the box.  Second time failed to oscillate, contacted manufacturer. Stated to return item. Package in box, drive to Post Office and pay freight to return. So approx $51.00 for the item, $16.00 freight back and wait for either a fixed or replacement, in a heat wave. Other than the cool factor of the sprinkler. The performance issue and cost to actually have to pay the return freight outways purchasing a cheaper (much) item that actually performs as well.
