I have the Enlan EL-04MCT, SRM7063AUC-LI, and Ganzo G712 and 720-OR with the G717-OR and G704-BL ordered.
I have a couple more SRM7063’s and an older LB-763 the SRM Axis lock on those models is by far the best on any of the others that I have smooth and not too strong an spring.
The Enlan EL-04MCT is basically the EL-04 but with Micarta scales, great grip without ripping pockets. The Ω springs were much too strong to be comfortable, for me anyway, so I took the scales off and bent the Ω springs so they’d have a weaker effect on the lock bar. Not difficult if you have some Torx bits, T6 and T8 if I remember correctly, it might all look complicated but it’s not. While I had the blade out I stuck in some phosphor bronze washers, 20 thou. per side, oiled everything and a dab of Molybdenum grease (black and very slippery). This has resulted in a blade that can be shaken out and locks firmly. You don’t have to do this to have a very good knife but I had the bits and pieces so I used them. The lock on the Ganzo G712 isn’t too bad but the G720 is a bit too stiff and I’ll go down the same route as the Enlan soon.
Ganzo quality control can be a bit hit and miss, both mine have had pivot screws (one each side on a Ganzo) that turn easily with a bit of force but some people have had one side that will not turn, not even with heat and lots of force, meaning that you can’t strip the knife properly. The blade tang on my G720 is machined slightly oval in a part that should be round, it will be easy enough to remedy but it means the blade is a bit reluctant to pass a point near where it is closed (about ¾”) then really snaps shut. It isn’t as noticeable when opening because it’s about the point where your thumb has the most power on the thumb stud. The Ω springs are too strong to let the blade swing free comfortably although it can.
I haven’t heard anything bad about Ganzo’s 440C but given the optional quality control it’s a good job that the steel is bought in.
I’ve been so impressed by the G720, even with it’s flaws, that I’ve just ordered a G717 and a G704.
The clearance between the blade and liners is amazingly tight for a production knife and stayed like this even after adjusting the blade to be a little bit looser.

So I ordered the 717 and 704 so I’d have a better idea of the quality and fit/finish, two knives isn’t really enough to give an overall picture - four will be better.
I do have 6 G620’s but they are a different type of knife completely, and a separate series, less costly and assisted opening - all but one was fine out of the box and the sixth I stripped, greased the A/O spring and re-assembled then it was fine.
FastTech have absolutely no control over what happens to the packages once they’ve shipped it - every Chinese vendor is at the mercy of the postal services. At least FastTech let you choose carriers, though your choice is limited with knives to postal services that will carry them. FastTech is my first stop for knives because the price is usually the best.
EDIT - I just realised that the shipping to the U.K. would be completely different than to the U.S.A. so not comparable.
