Customer Reviews
August 25, 2023, I purchased UVA LED chips from Learnew. Learnew delivered the custom UVA chips we requested quickly and with excellent workmanship. It was a pleasure to work with Learnew. He was able to tell me exactly which product would work with my curing printer, saving me a lot of time. They are very professional.
