I have purchased the ganzo 710, 712, and 716 models. I also have a benchmade 710 in d2, a 710 in m390, an 810 in m390 and a griptillian in 154cm.

Other than the quality of the materials here is what I noticed in the Ganzo knives: 1. The springs on the Ganzo axis lock is MUCH stiffer it hurt my fingers with prolonged use. (Maybe I have weak fingers) 2. Inconsistent smoothness of opening/closing. The 712 was EXTREMELY smooth. Much smoother than any benchmades I have handled. The Ganzo 710 and 716 were not even close to the smoothness of a BM or the Ganzo 712. I don't think it's related to the specific model. It's more likely just related to their QC. So you may or may not get that "just right" one from the lot. 3. Uneven grinds. No I don't mean uneven grinds on the edge. I can fix that. I mean the swedges they put on the spine of the knife are uneven. On my 710 the left side of the knifes swedge was much larger than the right side. No, it doesn't have an effect on the performance, but yes it bothered me. Although it's alright since its just a 20$ knife. The uneven swedge on the 712 was so bad that the spine was not even centered. It was off to one side and really bothered me. Now this is just a cosmetic issue and the knife will work just fine despite any of this. (I can post some pics if my description isn't very clear)

Since I didn't care about them I tested them with some heavy spinewhacks. I was actually quite surprised that none of them failed or showed any sign of issues so I could say that the locking mechanism was pretty solid and there was next to no blade play at all.

Long story short: For their price they are good performers with an axis lock mechanism. The biggest downsides are cosmetic and comfort kinda stuff.
