Astrolux S1 Problem

I’ve had problems with an S1 since I’ve had it and have had a return approved via Amazon … just before I do send it back I thought I’d see if anyone can shed any light on what may be wrong with it as it’s such a hassle sending it back and then having to wait a month to get a refund to then order another which will probably take another month to arrive.

It’s been very intermittent whether it’ll work at all but the times I do actually get it to switch on it stays in the mode it’s in for 5 / 10 seconds then steps down to the next lowest mode, then the same again and repeats until it’s off …. I can half click and it takes it back up a mode but then does the same again.

I’m guessing it’s probably the driver that’s faulty???
