Hmmmm... I just know that I'm wading into a pile of shit here, but maybe this topic needs a bit of perspective...
I'm happy as hell with my Kenometer. It's the best money I ever spent on laser-related goods and increased my enjoyment of this hobby, and my knowledge of my lasers capabilities immensely. That being said, I can afford a good thermopile meter (and had the time and opportunity to verify it's accuracy vs. LaserGlow's high-end meter).
jamilm9 is a 10-year old enthusiast who lives far from the nearest meter owner and has to scrimp to save for even a Laserbee 120mW unit. I'm spoiled with my Kenometer, but a young guy like him can't spring for a good meter. Even if the Laserbee sensor has errors, all that's required is for someone with a good meter to make note of the error factors, by wavelength and power level and make a chart to correct for those errors.
Factoring for sensor errors is too bothersome for those of us who own good meters, but for a young fella with no other option, it's a small price to pay to have an approximate reading of his lasers' power. Remember how in the dark you were before you had a meter, and remember how enlightened you were once you could see exactly what your lasers were doing? He deserves that same enlightenment.
I've asked Laserbee to ship me a sensor for review. If he chooses to, I'll make a chart showing the error corrections vs. the Kenometer for the 5 wavelengths I own. I'll also test my higher powered lasers with a 50/50 beam splitter to see if that works. Even if the product is inaccurate, the error can be corrected for and those of us with fewer funds can have a better approximation of power at a more manageable price.
It's the fair thing to do.
