Faulty Flextailgear Zero R05 Mattress.
**UPDATE** I eventually got a reply after several attempts to contact them and they will send out a replacement. **END OF UPDATE** Purchased a Flextail zero R05 mattress via their official Aliexpress store. It arrived in good time but unfortunately, after it's first use on a camping trip. It wouldn't hold air. As it was after Aliexpress's return window, they said they couldn't help and that I should contact Flextail direct for a warranty claim. Flextail have thus far failed to answer my numerous support requests. I am now £80 lighter with a product that's faulty. If you're thinking of Purchasing from them, think again!!
