I signed up and received regular emails with offers. Went for a Mystery box box for 12.99. The image portrayed a number of gadgets, I wasn't expecting top grade goods, but I was expecting to get value for money
I paid £12.99 plus £4.99 postage. I haves added an image of goods received. Two of the items were doubled up. Total value probably under a fiver. Only one useful item in the box and all poor quality.
I can't say that all products offered are going to be of low quality, but when you look at the sale price against the alleged recommended retail price, the discounts are so big you have to wonder if they are genuine price drops and not just cheap items with fake discounts.
I know it's called a mystery box, so there is some luck involved with what you receive but ensure they don't contravene advertising standards they should change the name from Mystery Box to Disappointment Box.
