I think a lot of the problems with NTX stem from a lack of proper communication and transparency as to how their ordering/shipping process works. It is not an Amazon experience, but they resolved all my issues and left me with confidence that they ARE out to operate legitimately.
Since the problems, they shipped a bunch of loose GearWrench parts I ordered, two GearWrench torque wrench promos, and I just bought the last set of flare wrench promos in stock... no issues whatsoever.
I haven't really had a chance to put them to the test yet, but my first impression is positive. They are very heavy with beefier heads than the SK's, a lot like the Snap-on flare nut wrenches I've handled. Overall they feel like quality tools. I've attached a couple of side-by-side pictures with an SK wrench - hopefully I'll actually have a chance to use them here shortly.
I got mine yesterday... online they suggested I place the order via phone as it was the last one left, to ensure I got it.
12 nice GW flare wrenches for $39 (or $49 with shipping) you can't go wrong. I have the USA Craftsman RP set I bought from a member here, and an add-on Snap-on in the 5/16x1/4 size not offered in Craftsman RP (it was cheaper new on eBay than the Craftsman full polish replacement).
The GW head in the same size wrench is substantially beefier than the Snap-on, and beefier than the Craftsmans in the other sizes. This may present an issue in tight quarters, time will tell... probably never for me as I'm not a mechanic.
This is quite the deal. They are now out of stock from that distributor (who also is probably the stock for the networktool site referenced, as well as Citrus Tools) but if they come back in, pick up a set!
