My 521 SUCKS! Wasted much money for a $49.99 rda build stand
I bought my 521 when it first came out. Though it was a great idea. About two weeks into using it it would not read anything I put into it (like the pin wasn't making contact) so I put in a heat sink to finally get it to work. Lately though it dosen't seem to read anything under 1 ohm. I expected a lot more from Coilmaster. I hear it's a real hassle dealing with them to get something returned. I'd settle for a working 521. Can anyone help me out there!!! Please contact me by email I don't think I can find this post again.
