After using it 4 months, wire near USB connector had problem.
Connected and disconnected... charging.. then not charging..

It worked well, but I cannot recommend this since the life of product was only 4 months.

It's been exactly 4 months since I purchased this product for my Roomba 650.  It worked well for the first month.  And battery life has deteriorated quickly since then.  Today, the Roomba lasted 1 minute.  I tried to email the company last month for a replacement but no response.

Edit: Customer service sent me a new battery after I gave a 1 star review.  I tried asking for a replacement before the 1-star review and they said I had to ship the old one back out of pocket first.  Seems like lopsided customer service IMO.

Bought a remanufactured Nitrus for a bargain price, but it was no bargain.  It died suddenly and for no apparent reason after seven weeks - no wonder they only give a 30 day warranty!  It's a real shame since the design, sound and features are great.  Yes, I read the reviews so I knew about the reliability problems, even with the new (non-refurbished) units.

I figured that if I took good care of it it might last awhile.  I was wrong.  Caveat emptor, indeed.

This is the second one I bought.  At least the first one lasted almost a year.  This one, 4 months.  That is ridiculous. I love the product but NOT WORTH the price for 4 months of service.  And, I'm not talking about a lot of use, maybe once or twice a day.  I gave it 2 stars and not 1 because while it works, it's great.  But then it suddenly stops working, out of the blue.  The first one did it, and now this one did it so I know it's the product that's faulty.

While I Thought This was a Good Product, It Only Lasted 5 Months. It was Very Difficult to Change, I Would Like to Have Information About The Manufacturer, as Amazon (Seller) Only Has a 30 Day Return Policy on This Item!

Cheap materials = short product lifespan.  After a little more than a month of usage for several hours per day, the middle fan has started making a squeaking/clicking noise AND the extendable piece on the side has broken.  The unit is still usable, but not on the highest setting (since thats when the middle fan operates noisily).  It is also no longer stable due to the broken extender, and instead relies on the window screen to stay in place.  I have not been particularly rough in handling this fan, and have taken care to keep dust from building up on the fans, so I am disappointed that the product only lasted this long.  I definitely DO NOT think I received my moneys worth out of this purchase.  After seeing that my return window was only 30 days, I realize that this product is intended to fail and I should have paid more attention to the warnings by other customers.  The only reason Im giving it 2 stars is because it looks cool.

My 2 year old B&D Leaf Hog just died... burned out power head circuits.  While it did a good job while it lasted, it didn't last very long.  I've had similar experiences with other B&D products: drill, router, coffee maker, and toaster oven.  Good functionality, but short product life.  I'm done with B&D.  I just ordered a Toro replacement for the dead B&D leaf blower-vac.

Twist arrived late January, used it about four times and it worked great.  Used it yesterday, early April, however lid arm broke before it could open the jar.  The device can no longer be used.  The concept is sound, but the product construction is plastic and does not handle the stress as well as it might.  Hard to recommend the product when it breaks so early in the lifecycle.

I purchased this extension to use once per week to unload pictures from a dslr to the computer, where the usb is in the back. I woke up the computer to load as usual, but before I could plug in the camera cord feed, the computer noted a power surge at the port where this extension cable was plugged in. The extension cable no longer works even though I used it about five times. Of course its past the window to return/ exchange. It wasn't a lot of money however I wonder how well it is made. Plus, the short life span of the product is super inconvenient.

I purchased this set in November of last year. Today one of my headlight went out. I reached out to the company for help and there response was sorry we have a 90 day warranty, there is nothing we can do to help you. I advise against this product and would not purchase again. The life span is too short, A headlight should last longer than 9 months. Most headlights carry a 1 year warranty.  I do not recommend this product to anyone.

Sadly, this product failed after only 4 months of very light use. It worked great while it worked but now it's dead. Will try to get a replacement under the manufacturer's one year warranty.

I have had this product for a little over 4 months and the box has died. It worked well when it was working but
this product is not long lasting. A piece of junk.

It's not an in-your-face product, but it did not last very long.

The product worked well, but stopped working in the 4th week.

Bought it and it worked fine for about 4 months. Not very loud, but it worked. Then one day, it died. Never powered up again. I am going to try the Cellular Innovations headset next. If you want a temporary solution, this might work, but it is likely to die on you.

I ordered this product and it worked great - for only 4 months. At first it started working intermittently and then within a few days it completely stopped working. I attempted to use it on different wall adapters, but that didn't work. The cord completely died. 4 months for a working product is too short
