Absolute pile of cr*p. bought an adjustable desk as it seemed like very good quality. 1. Top part arrived within good time, bottom part was then lost apparently. After 2 weeks, when I said I wanted to return top because they couldn't give me a suggested arrival time I was told I'd have to pay for return myself!!! They eventually conceded and agreed to send replacement legs which arrived within a few days. 2. In any case, top part had a massive dent in it once it arrived. 3. Legs eventually arrived but: 3a. one of the screw holes was defective so the screw won't go through it and metal stand therefore not entirely secure 3b. holes on underside of top didn't align IN ANY WAY with the legs. Was told that in order to get this fixed I would have to go through some laborious process involving making a video and sending everything back (no doubt at cost to myself). Deciding that it was easier to just make new holes myself, I did. And eventually attached legs to top. None of this should have impacted the adjustable mechanism. Table worked fine in terms of moving up and down. FOR 2 DAYS. Having not touched it over xmas (about 8 days) I have gone to start work and the mechanism is no longer working. Have tried resetting, and followed all advice for troubleshooting. And the power pack just clicks. Personnel working for ByKellevig perfectly pleasant, but the product is a pile of nonsense. I am soooooooooooo disappointed. Now I have what is effectively a standing desk and completely the wrong height and a sore bank balance. total and utter nonsense.
