Deliberated for a couple of days after my nurse dropped my previous curing light and snapped it in half!! I did consider getting the same (woodpecker i-led ) or similar one for circa £150-£200 . Luckily I had an old spare one which I used in the meantime. Watched and read a few reviews. Could not have been happier with my decision and the service received from Toothsaver. I had seen the O-Star at one of the shows and spoke to Daniel so I knew it was worth a few extra quid! Compact, lightweight , easy to rotate, different settings etc , good battery life , A thumbs up from me.
