Thumb and fingers are a bit loose but not too bad.
They look great and give you separate fingers

Pop off, pop on. Done. You can also use these on Wheeljack with some (a lot) of filing on his peg, and a LOT of work on his stock hands to remove the fender piece... keep test fitting on these hands with Wheeljack transformed in car mode to get them right, then glue.

The fingers ands thumbs constantly came apart from the hands( after only 3-4 uses). nothing would make them stay together. Terrible product. No replacement offered. I would give zero stars if I could

The hardest part about this install was removing the original hands - I thought I was going to break the peg they attach to off. Once installed, these new hands are a vast improvement. My sideswipe can actually hold his gun properly, and the extra articulation makes for better more fluid poses.

Like it says up there, good stuff.

Tiny, fiddly fingers you can lose in a second, but such an improvement.

These poseable hands are amazing. The quality is top notch, the finger joints are nice and will hold any position you put them in, the hands still fit perfectly inside the arms for transformation, and it took a grand total of three minutes to swap the originals for these! I will definitely be upgrading any MP I can!

They work great. Very posable. It makes him hold his weapons better.

The package comes in a little resealable bag, and no box and instructions on how to install them.

However by looking closely and how the original hands are installed you can pretty much work out how to dislodge it without breaking your figure.

The quickest way to remove the fists is by having the groove of the hand swivel face down and use the edge of a table as leverage to push out the hand. You will not be able to do this by hand.
From here it is a matter of sliding the hands onto the swivel and you are good to go
