Great idea. Not at all durable.

We bought this for our 5 year-old for Christmas. She has now owned the headphones for exactly one week and the right side already produces no sound. She is admittedly not the gentlest child with her things, but she's probably used the headphones for no more than 3 hours and has not been doing anything unusual with them. She used them around the house and in the car only to listen to her iPod shuffle.

On the pro side -- the headphone did fit her well (we'd tried kids' earbuds before and they are not as good a choice for little ears) and the purple matched very nicely with her purple iPod shuffle (fwiw) but she could still get pretty loud volume out of the headset. We did find ourselves telling her to turn it down.

But the deal breaker is that it is just not sturdy enough for our kid. Like another reviewer said, the plastic is pretty flimsy.

So here's the thing. I love this toy in concept. It zeroed in very smartly on our dog's behavior. He loves chewing bottles. And I know that toys aren't impenetrable, but honestly the cover was tearing apart within the very first use. I don't have a big dog, he's a jack Russell terrier mix, but we had to take it away 10 min after giving it to him because he was chewing off pieces of the foam cover and eating them. Love the concept, the toy needs to be tougher.

I love the concept of the collapsible containers for storage, but I used mine only a few times before the bendable part separated from the hard plastic.  Very disappointed.

I don't know how many of these I purchased over time and all of them broke within a couple months.  Fortunate most of the time I found the dogs tags in the house hanging from the broken Rubit and didn't have to search through the yard.

It's a great idea, but the product quality leaves a lot to be desired.

For the record I have tried these with both my Giant Schnauzers and my Mini Schnauzers with the same result.  They break in a few months.  So if you want to use these, have back ups and plan to replace them frequently.

Cool idea. But after a couple hits each ball broke on the seem. If made a little stronger to be able to actually be hit would be great.

Unfortunately this thing is not very durable. It broke quickly. The connections could be way more secure. The idea was a good one but it won't last long. I promise this will be over with your first crash.

Awesome idea... cool at first... a small piece of plastic will break off in the inside that holds the spring in and it will become useless,  but since it's a 3 pack,  you might get 3 months use out of it..  I've ordered these 3 times.. gave 3 away... same results with all of them

This hose solution is a great idea -- I really like the included bracket that holds the spray head. But I bought four of them and the hoses all fell apart within a year. Product simply doesn't last long enough to make the purchase make sense.

These are a great idea but real world they break down so quickly you have to replace twice a week.

these are a great idea but in my opinion have priced themselves out of the market. They are not durable and can't really last with too much handling, I am not talking playing them as my nine year old did with his, just easy handling and switching of accessories. items broke far too easily. Don't waste your money.

Great idea but they just don't last. Have had a few of these and they are great for a few weeks but then burst.

Can confirm that this is a great idea poorly executed. It requires frequent attention to keep from completely coming apart. After the first week the plastic hinges began breaking, one by one. I will modify it to give it a bit more life, but I'll look for another solution rather than replace it when it finally falls apart completely.

The idea is clever and a good one. However, the implementation could probably be better. The main problem is due to the poor durability of the plastic. It bends and crumpled too easily. By the time I finished my 2nd fork, the plastic was so bent and torn that it could not be used. I had to cut it up into a possibly reusable shape. I don't think I will buy it again. There is probably some material that I can find at home and use it instead.

I loved this tape measurer at first - so much so that I bought 2 of them.  I thought this is how a tape measurer should work. It worked perfectly for about a month and then the spring mechanism that keeps the tape extended wore out so that automatically retracts like a traditional tape measurer.  Problem is pressing the button makes it even worse since this is what it's designed to do.  I really like the concept but long term durability is not so good.

The concept of this product is wonderful and it worked great for the first 3 months.  With that being said, I am currently seeing major issues with it and am ready to throw this thing out the window.  The propping up of the iPad is nice...until the velcro doesn't hold anymore.  A short term "duct tape" fix is to apply additional velcro strips for the iPad to grab.  Eventually those strips can't hold onto the inside of the cover either and come off.  Next up was the keyboard.  A virtually perfect keyboard for an iPad.  After 3 months of use, using it occasionally about 3-4 days a week, the keyboard is completely dead.  It won't hold a charge for longer than 10 minutes, making it unusable.  The reason I bought this product was so it would get me through my long meetings without having to carry a bulky laptop and power cord.  If I don't have the keyboard, why bother.  The third and final issue - the external material is getting ripped up along the folding edge.  Once you have a small tear or worn out area in the material, you will soon have a large one.  I am currently looking for a new solution and it will NOT be a Kensington!

Great idea, but they are not durable whatsoever. Running with them ruins them almost immediately.
Also, the light was very dim, even with brand new batteries. I bought my first pair at Costco, and they were so much brighter. But also got ruined in motion.

I purchased this because my suction cup holder wore out and didn't work anymore.  This was a great idea, but the plastic clips are too small and one of them broke almost immediately.  I glued the broken one back on, and the other clip broke.
