I received the laser LC/40 I received the laser, I tested it. Now everything is ok. It works perfectly. Thank you for the professionalism you have shown. 5 star technical support team. I recommend with confidence.

Sainsmart puts the pro in 4040 pro! The inside of the USB port on my 4040 pro broke loose and came out. Sainsmart sent me a new board. When I put the new board in it was defective. Sainsmart rushed me a board and everything is great! Sainsmart is hands down one of the best companies out there. I will look to see if Sainsmart carries an item before I purchase elsewhere. Sammy and the customer service team are amazing! They absolutely stand by their products and care about their customers! Thank you Sainsmart for all the amazing work you do!

High quality Sainsmart makes high quality CNC machines for a variety of applications and their customer service is friendly and timely.

Problem resolved. I had problems with my machine, but the support team (Jamie) sorted everything out in a very helpful and speedy manner, going the extra mile to get me up and running. One of the best, if not the best, dealings I have had with any support team.

A happy customer in Spain. Great service and good communication. Customs fees included in the price of the item to avoid problems. A happy customer in Spain. ⭐⭐⭐⭐⭐
