They are fine as long as you are based in the Uk but don't order if you are abroad especially expensive item. My tablets were delivered completely crushed by Dpd I had to throw them away. Dolphin fitness doesn't give a damn about you and won't give you your money back. Should have put it in a box at least not in a stupid jiffy which someone stepped on. Will call bank and try to recover lost funds. Customer service is beyond shocking. They are just completely ignoring my emails. If it's not enough that I'm sick and don't have my tablets, I need to put up with this (non existing) customer service on top of everything. Thanks really.
