No MAJOR complaints, but this wasn't a SMOOTH transaction.
Got the mask at a good price, but when I got it, the lense was cracked. I'm assuming he tried squeezing it into the box as best he could, and just bent the lense to far. No biggie, Stuie said he was going to send me a new one.... A few days later, upon asking (mind you I had to do this myself), I'm informed that "His mom" didn't mail it. So Stuie refunded me $15 to buy a new lense.
Had he just told me in the first place the lense didn't get shipped, I'd have no complaints. He is a nice guy, won't scam you, just needs to get a little more organized.
Bought a gun from him and was told it would be shipped out on sat. july 30th with a tracking number. Asked on monday where the tracking number is, and did a search of his posts. He was buying a part in the B/S/T forums for the marker he supposedly shipped to me sat. I asked him what happened and he lied saying he noticed the problem on the shipping date (He had already bought the part for the gun I bought from him on the 26th). He gave me a full refund and apologized.
