This company delayed the delivery of our system for more than two months and caused us to pay a large amount of penalty fee to our funding agent. You are advised to clearly set a penalty clause on the contract with this company for late delivery.

This company recalled a set of mid-IR OPO mirrors from us due to peel-off of the coatings, but never returned us the mirrors or the payment.

This company shipped us a 200 mW green laser, which worked for less an hour, but refused to accept our return of the product for repair. The problem appears to be linked to the difficulty of handling returned goods at the Russian customs.

This company asked a full pre-payment from us but (1) delayed the shipment of the products by nearly 4 months, (2) shipped a product down-graded  from what we originally ordered , and refused a replacement. Please note the difference of the touch panel and the 100 Hz etc. of our original order STLDF-35-QBD and the push bottom and 50 Hz etc. of the shipped FLD-4U-SINTEC1 . In addition, the dimensions of the shipped laser rods are larger than the aperture of the pump chamber, causing chipping to the rod surfaces during our in-house installation. The aperture of the shipped connectors was also too small to be connected to the pump chamber electrodes. We had to self-machine a new set of connectors for the pump chamber. There are apparent quality control problems in this company.
