Tracer 20W Laser Power Meters - Sanwu Lasers

I ordered and received my 20w lpm, it was packed very nicely and the delivery was prompt. On to the meter, I have a 10w, 7w, 5w, 2w lasers, all in 445nm. The meter worked as described, the only negative is the there were no instructions included, one would assume that if you pay $350.00 there would be instructions. So I tried using it anyway, for obvious reasons I was limited what I could do but for what I did do, it worked fine. I reached out to Sanwu via text, they immediately responded with a link to the instructions, I opened it, saved it but haven't use it as yet. The instructions are straightforward but not very detailed, it would be nice if Sanwu did a short video of the use of the lpm. That being said. I give it a 10/10 and would definitely recommend it, good job Sanwu, as stated they do need to do a video, that would help tremendously. Herb

Power meter ordered on september the 12th, 2023, announced with a 60 days manufacturer lead time After 3 months, still no advancement from Sanwu Francis (Sanwu's commercial) told us that production should begin soon, but on January 2024 we learn that some components are missing so the product won't be the same as what we ordred (not a LCD display, but a Bluetooth connection, that we don't want). 3 weeks ago, Francis suggest a refund we agreed on, but still waiting for it and for Francis answer. So if you are wondering if you should buy this product, think twice. Sanwu's comunication is not really good (sometimes you have an answer in a day, and sometimes you won't get an answer). it's a shame because the product looks good and is affordable.
