Terrible experience with this vendor . I placed a $550 order with them for 10 g sample, they only sent me 1.5 and refuse any kind of refund besides to wait until their china warehouse begins delivering to US again. At the time of the order they quoted me prices for the 10 g sample after I sent the money they now say their US warehouse are only offering kg. Also they’re acting like they actually did me a favor for delivering the 1.5 instead of the 10 gs that was agreed upon. Order at your own risk …. Haven’t tested the mag yet took 11 days for domestic. They have treated me like a piece of shit..
