I just purchased a 4x8' laser through them. Support has been fantastic. We had some issues with the laser after install (Which is nothing new with any Chinese laser) and they went 200% above and beyond to make sure it was fixed. We own 3 Rabbit Lasers and never received this kind of support from them. Thinking about selling our 3 Rabbits and going to Boss simply because someone is there to answer questions when we need them to. I suggest giving them a ring.
