Hi Thanks got delivered before expected date, This I like even on International delivery you got deliver before time.
I had checked and found product is working satisfactorily. Nice Heavy Built heat sink with good airflow by fan.
Even Driver circuit i like it performing well.
What I had done to extend the life of using laser more in engraver I had used heavy massive Aluminum Heatsink 10"L x10"W x 1" Thickness with FINs.
Now you can use the laser module in engraver machine up to any time you like.
Now you don't have to wait to cool down for completion of job.
NOTE: No restrictions of only 30 minute use. Use Thermal heat paste of Thermal conductivity of 2.5 W/(m·K) between laser module Heatsink and Bigger Heat sink.
