Slap chop. Tried slicing already sliced apples and it just broke

That big belt you wear around your waist to help you lose weight. I was 17, spent nearly 6 month’s savings on that thing.

Anything that is supposed to remove hair permanently. Or restore it permanently.

When I was a kid I remember seeing a commercial about a remote control car that could drive on the walls. Of course I was fu*king amazed. Turns out it was a 10cm long car that had a vacuum system built in, made a lot of noise and was super slow

I hate chopping vegetables so I bought one of those automatic things they show on TV. A whole diced onion in 30 seconds. It mainly just smushed everything and got clogged up and took forever to clean. Turns out a knife and cutting board is easier.

The “inaudible to humans” cat deterrent devices you’re supposed to be able to hide in your garden. It was really loud and piercing and utterly ineffective. I eventually gave up and got a cat. Now only one cat poos in my flowerbeds, which is an improvement, and I know what he eats.

Pedi Paws, that rotary nail file for dogs. It would have taken at least 20 minutes of filing per nail, and no dog is going to hold still that long! What a waste of money!

Burgers and other fast food when you see it in advertising billboards and then are disappointed by the actual food.

My son, who bought an awesome Tag Heuer watch in Chinatown for $10. Real nice, 3 dial watch, for seconds, moon phases, and who knows what else. But, while we were driving home he blurted out from the back seat, “Hey! These dials are just stickers!”

Tooth whitening kit. Comes with some gel and a blue LED thing you put in your mouth for a few minutes twice a day. Used it for two weeks with absolutely no change, €30 down the drain.

There was this ham that had commercials especially addressed to kids. It was saying that if you take a bite, you go on an adventure. It also showed the kid that ate it teleporting into a spaceship and going on a space adventure. Bought it and… It was just a regular ham.

A teddy toy. I begged for that thing and finally got it for Christmas. In commercials, he looked like a cuddly stuffed animal who talked to you. In reality, he was a rock hard cassette player covered in a thin layer of felt. Snuggling with that thing was like trying to cuddle a vehicle transmission. He was heavy and only worked with special cassettes that cost 4x what a regular tape cost, so the one he came with was it for me. The story was boring, and I lost interest in it almost immediately. Worst thing was, the mechanism that moved his eyes and mouth were incredibly loud. You had to turn up the tape volume all the way, to cover up the buzzing and clicking. Total disappointment, man.

Those blackhead cleaning/pore sucking machines. I got a mid range one, used it how the directions instructed, and all it did was leave my skin red, no visible pores cleaned whatsoever. Totally useless.

Every mascara ever. “Your lashes will look LIKE THIS!” …if you were born with them like that.

A hard-boiled egg maker. You usually see the colorful Dash brand ones, but I bought a Cuisinart one that had a metal lid because I thought it was made of better materials and would, therefore, last longer. It is the most awful kitchen gadget I’ve ever bought lol. All it does is blow up the eggs and then leak eggy water all over the counter. I followed the instructions. Same result multiple times. All because I am too lazy to boil water in a pot!

When I was like 6 or so, there was a commercial for transformers underwear that came out just before Christmas where the kids wearing them could transform. They were the only thing that I asked for Christmas that year. I forget what my parents/Santa got me, but I distinctly remember being disappointed that it wasn’t transformers underwear. Later that day my grandparents showed up, and when I opened the transformers underwear they got me, it was by far the most excited I have ever or will ever be in my life. I went to the bathroom and put them on, then went back into the living room and proceeded to try to transform in front of my family while they laughed at me. I remember my grandfather joking “maybe you need to plug them in first!” That is easily the most let down I have ever been by a commercial.
