This is the only 1 star review I have ever written...

This is the only 1 star review I have ever written, but I must be clear and warn others... I do NOT recommend any Ultra Light Optics product. I've had nothing but problems with this light since I got it in 2016 in dental school. I have had to pay full price to replace the battery several occasions with the "one year warranty" having just expired (once the week of my boards exam). I just called to get a replacement battery because, of course, it stopped working unless it's plugged into the wall. At least this is an upgrade from it stopping entirely, which has happened many times previously. I also have had to replace the bulb, which supposedly has a lifetime warranty. Additionally, the cord has had to be replaced twice already in 4 years. I'm done with this company, I highly recommend looking elsewhere for your dental needs. I can't afford to continually be without my light for days on end and believe it's a disservice to my patients every time I am forced to be without it. I am immediately investing in Lumadent, as I have several colleagues that have been impressed with the quality and customer service; two things Ultradent is entirely lacking.
