This is the Yabangbang YB6 dental handpiece, and it's a solid piece of kit for any practice.

It's a standard head, LED fiber optic model—so you get bright, shadow-free illumination right where you're working.

It's brand new, unbranded in terms of a big name, but it's got all the important FDA registrations: K192233 for the curing light function, K181691 for the handpiece itself, and even K163414 for the scaler compatibility.
So yeah, it's cleared for use in the US.

The YB6 model is known for being reliable without breaking the bank.

If you're setting up a new operatory or just need a backup handpiece that performs, this one's worth a look.
Standard head size means it'll feel familiar.

Check the numbers if you need to verify fitment, but this is ready to roll.
