Amazon dash, personally yes I think it's a great idea. Essentially it's a push button that auto orders things for you so like toiletries, condoms, fairy liquid.
Now I think awesome that would be handy, but then I saw the price they are £5 each so to put that into perspective you would need one each for:
Toilet paper
Deodorant
Mouthwash
Toothpaste
Shaving cream
razor blades
Shower gel
Shampoo
Washing up liquid
Washing detergent
Dishwasher soap
Etc
That would be £55 plus the £80 prime membership you need to even order the items you need.
In a way it's a shame I could imagine this becoming a really useful product that could generate a lot of sales for Amazon with so many people having these buttons in their house but I can't see many people paying £5 per button
