lol i didnt say they were a 10, and i didnt advise him to buy it, i simply stated that they do work, like i said i own 2 and they do a decent enough job for me, as far as a year before the chip burns out well... I couldnt tell ya, havent had them for a year, ones 8 months old and one is about 6 months old, all i was saying is what I can say from my experience with them, and my experience with them hasn't been bad, unlike my experiences with other Chinese manufacturers, lighthouse hydro, joyhydro, mars, koties, and stealthgrow.... Hell I like these better than my lushlighting unit that scrapped out in 7 months, true I got another from them free of charge and that unit works fine, (although as of now it's on the sidelines as a backup) and also I'm not running a full tent most of the time, 4 plants is tops for me, I never said he couldn't do better, I simply said they do work, they are capable of the full life span and can do a decent job, he wanted a opinion I figured I could give my honest feedback from actual experience with them and not just saying oh it's Chinese so it's shitty.....
