I'll start by praising the Iron Man 1000 carbon fiber frame but this gear has many weak points:
They rotates as there is no fixation in the upper part of the legs.
For the same reason you may lose them.
The horizontal part slides forwards and backward from time to time.
The "rivets" used to be able to fold the legs are made of weak alu-type material. They become sliced to pieces by a little force on the legs. I had to replace them with stainless screws and lock nuts. It's quite obvious what a small force on the bottom of the leg will do on the rivet 10mm from the top.
The plastic holding the horizontal parts! This small piece of plastic has no possibility to handle the force by landing if the landing isn't exactly even (and when does that happen :-)
This connection point is by far the weakest point of the gear.
An issue with the gear is that it's stiff! Carbon fiber is very stiff so the only deformation zone is the rubber end at the end of the horizontal parts. This is by far not enough when you land several kilograms.
I have removed the gear and replaced it with four foam cylinders close to the motors of every second arm. It's not as good looking as the Tarot gear but it works fine.
Swedenlove the slide lock but there is a bit of slop when locked in the down position
