Did not last more than a few hours.

The lights seemed good at first, with no duds.  However, by the end of the party about 1/3 of them were out.  I would have thought that they would have lasted more than 2 1/2 hours.  I'm not sure why there are so many 5 star reviews?

I purchased this toy last year for my grandson who is very interested in tornados. The kids loved it but it didn't last much more than a day.  The control knob stopped working so no tornado.  Sound was the only working part.  Other reviews mention that it eventually began to leak from the bottom.  This one did not last long enough to leak. Neat toy though during it's short life.

Unfortunately we did not have as good an experience with this unit as many have!  It stopped working for us after only about 6 hours use.  Whereas it was not unattractive while burning at night, we found it very plastic looking during the daytime!

Our puppy loved playing with it, and only had it for about 3 hours before it started to badly unravel. She wasn't even playing rough, just really gumming at it. A real disappointment for the price.

This cat toy died in 2 hours. After I replaced the batteries (the replacements one comes with this toy) It worked 3 hours and died again. After I changed the batteries LED stopped working, the toy just rolling around.

Actually it didn't work properly after the batteries were replaced. It had some issues with rolling.

Save your money. Buy something else.

My son had this for twenty-four hours before it quit working. Autopsy revealed that the negative wire is just barely long enough. One decent crack on the ground, and the soldering pulled apart. Nice idea, cool set-up with the removable battery pack, but a waste of money. Just buy a real flashlight (the Ryobi 18 volt is actually LESS than this toy at Home Depot).

The dogs loved it until it became a puff ball after a couple hours.  Thought it would be built to last.

Bought two for my boys for stocking stuffers.  Neither lasted more than an hour or two. They almost immediately sprung a leak with no unusual treatment.

As others have said, didn't last more than a day. Definitely not up to Kong standard.

Good for a couple of hours. Part of the costume started to slowly deflate. Could not figure out where it was coming from. Might try it again next year and try to find where it was deflating.

We bought these for a road trip and within 5 hours they stopped working.

The bulb was the right size and shape it only lasted for about 8 hours then blew, not even worth the few dollars it costs

Didn't last more than a couple of hours before breaking. See photos. I'm going to try and repair it with WeldOn. Maybe try to turn into a cute dinosaur or something. Back shield cracked and came off.

The glow only lasted about 10 minutes. Was expecting a much longer glow time. :-(

Battery was easy to install.  However, after fully charged did not make it through a full round of golf, and we play in about 3 hours.  Advertised around 12 hrs.  Not even close.  Returning mine.

Once I got it assembled,it lasted less than 24 hours. The elastic that holds the cushion to the seat snapped, and now nothing holds the seat up. I honestly wasn't expecting much for the money, but less than 24 hours? Come on.

Although it worked for a few hours, the tube started leaking again. In hindsight, it would have been easier just to buy a new inner tube for slightly more. Perhaps it was just too big of a hole to patch, but next time I may skip this step.
