Is this a good deal on a stepper driver?

the leadshine ma840h is a decent driver and has been changed to ma840e . I don't know how much I'd trust them on ali . They aren't going to be leadshine but for the price you can't go too far wrong .
I recently bought some of these as backup . I haven't had a need to try them yet but everything else I've gotten from these guys has been good .

I have their DM860T version (110v) and works great on 80vdc with a nema34 1080oz/in.
The issue with St-online is you have to be careful when searching motors. They have some really bad spec ones.

on the other hand they have some with really good specs , but I agree that a guy needs to be cautious in his choices . I replace my torus pro motors with some I got from them and the performance difference on the mill was incredible

I've got an equivelent of these ones:

At 3mh inductance they're not perfect but they reacted very well once I used 60vdc to drive them.
Now they have these ones:

I'll go for AC servos next time.
