It's sturdy enough and does the job without being too spendy.
One thing you want to know if you are planning to use this for converting the AZ-GTi into EQ: The screw for the mount plate is too large and will obstruct the mount from freely rotating.
I went down to the hardware store and grabbed a M8 bolt with hex head to replace it, so it's easy to fix, just something to be aware of.

I have an AZ-GTi mount I wanted to use in EQ mode. I debated whether to get this one from Sky-watcher or the more expensive William Optics wedge. I decided on this one and am very happy. It's well constructed and does exactly what its supposed to. As usual, shipping to the US from FLO was very fast, and just as fast as domestic shipping. Availability is better at FLO than what I've found at places in the states. I'll keep shopping at FLO.

Nice addon mount, makes any alt/az into eq
But beware the following
The bolt holding the supplied dovetail onto the az goto needs to be changed to something shotrer, maybe even grub screw as it will foul the goto while tracking
When using the goto do not set the inclination to your local value, it needs to be 90-your local value, you will not be able to polar align without doing this (mine needs to be set to 37 on the scale to align properly)
Once the alignment is complete tighten everything and remove the 2 az bolts, these can also foul the tracking

Dont be suprised when you try and goto if the whole lot spins round, even tho you are only moving sideways a bit, this is to allow full tracking (if you have ever used a manual eq mount before you will understand being a contortionust is a goid thing )

All in all a good product
Dont forget to buy the counterbalance weight and bar

It's good quality for little money
