I think the value is amazing, the quality appears to be top notch. However, without directions it’s going to take some time to assemble.
For this reason alone it rates a 2 star review.

I own a agt qh12 so I ordered the agt Hydraulic thumb from agt . Opened box check for instructions and parts. Bolts don't fit in holes had to reamed out holes. Bolts are to long had to shin . Finger and ram are mounted. Try figure where to mount the a/ b block goes. Block are the same hoses work right on one side not the other. Short fitting to mount hoses to block and wrong adapter to hook up to lines on machine. Had new hoses made.
No support from customer service never can reach anyone.

Love it. It works great.

I ordered the hydraulic thumb for my AGT QH12. You would figure that since I own a QH12 and ordered a AGT thumb then it would fit, nope. The auxiliary hoses from the excavator are DIn 16x1.5. The hoses they sent and adaptors they sent were both 14x1.5. So off to the hydraulic shop I go. Only cost me $190 to have 2 new hoses made with the correct ends. So now I’m $600 into a hydraulic thumb that isn’t even worth $200 in my opinion.

Now the thumb itself….. watch out for the cross member towards the middle of the thumb, it will smack the heck out of your hydraulic cylinder causing a big dent in the cylinder. And the bolts they send with it don’t all fit so I’m having to go out and buy new ones.

fit well, i made some bushing and had to get adapters for hoses, to be expected for a universal kit.
