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!

Great products I ordered from that side since the products have great price/quality ratio. everythink went well, fast delivery and products are as they where described. Support helped promptly at one occasion.

Really fast and adequate assistance Really fast response after request for help. They quickly offered the right solution and when the implementation failed through external factors, they immediately took action and solved the issue in a 2nd attempt. I'm a happy customer.

Damaged ER11 collet from set Company replaced the damaged item quickly and without issue with an entire upgraded ER11 collet set.
