I have received darn good service using this mini lamp. I’ll post pics of mine when lighting is better. Mine is kind of old and beat up looking as I use it a lot. Only downside is you have to do 3 or 4 fingers at a time. It got 5 stars because it’s easy to use. There is a heart shaped button. Push that button ONCE for 30 seconds or TWICE for a full minute. Cures all my gels.
