I've purchased a number of LightwaveRF products over the last few months (8 dimmers, 4 smart sockets, heating stuff, etc). Apart from some initial hassles in December where the order was delayed, I was pretty happy with my purchase, except for the integration with HomeKit, which is, to this day, unreliable and slow. I've opened a number of support cases and been reassured that fixes are coming. I'm still waiting more than 6 months later. Then, last week, my 3 gang dimmer stopped working. One of the 3 circuits got stuck in the "on" state, meaning I can't turn one of my light circuits off. I reported it to customer support, who had me try various things and eventually agreeing that it's faulty. They then asked me to return the dimmer (which is wired into 3 circuits) to them before they'll send me a replacement. This means, I've got to go and get an electrician out to remove the dimmer, put a standard one in, then wait for a new one and then get the electrician out again. I explained this to them and that I don't want to do that. The support person then wrote me the following: "We do require the item first I'm afraid, however, a work around if you do need it first, if you purchase another one from us directly, when we receive the faulty one, we can refund it, so you won't be out of pocket." This is an incredibly arrogant response which I find infuriating. This company is happy to take my money, but is not happy to stand behind the warranty they offer nor are the willing to fix problems. Instead, they are so arrogant, that they expect me to spend more money just to cover them in the (unlikely situation) where I don't send the faulty product back.
