The Useless box - This is the ultimate useless gadget. Once you turn it on, the useless box’s only function is to turn itself off again. You switch it on, the box switches itself off. That is the only thing that it does. Gadgets do not get any more useless than this.
Solafeet Foot Tanner - Ahh, the common problem of foot tanning. You want nice, tanned feet but you don’t want to go to a salon and you only want your feet tanned. You want to tan your feet while you work at your desk too. Well, with the Solafeet foot tanner you can have tanned feet in 7 to 14 days for the cost of $229 plus shipping. Incredible.
Morella umbrellas with cup holders - This design is intended so that you can carry two full cups or glasses as well as your umbrella when it’s raining. As you only have to hold the umbrella, you have a free hand to make calls, open doors and so on. But, it only carries two cups, and one simple mistake will lead to the contents of two cups emptied all over you. We’re not sure it’s worth the risk.
Auto-Exec Steering wheel tray table - Yes, this is a tray table that attaches to the steering wheel of your car. It only fits into the steering wheel when the wheel is upside down, but there is nothing to suggest you cannot use it while driving. We’d highly recommend you read some of the reviews on amazon for this product!
Sinclair C5 - The Sinclair C5 is one of history’s most famously useless gadgets. Less than 10,000 of this battery-powered one-person vehicle were produced. It had poor reviews and safety issues upon its release in 1985, and remains one of the biggest failing useless gadgets of all time.
