I own the setup.
I wished I would have purchased the adjustable legs. I didn't realize at the time I could buy the adjustable. I ended up buying the large size legs.
The setup is super easy to install, very light, not intrusive on the rifle.
I have taken it to the range and other than being jumpy after taking a shot (as expected with a Tika T3 Light) they work fine. I will say I don't do lots of shooting so I would not know when, and if they could break.
My recommendation would be to buy the adjustable legs or the Tricer legs if you can afford them.
Cheers.
