Manual impact driver

[jupiter joe]

Hello everyone !
I hope all are well
Just wondering if anyone has heard of a janmor manual impact driver
I thought at first it was a vessel same blue tin case but it’s a janmore
The only information I can find is an eBay post for one and they say it’s vintage
Looking for any kind of information
Thanks in advance

Janmor hand impact driver looks kind of like any other generic Asian-made hand impact driver. Are any of them "better"?

Anyone working on motorcycles, a hand impact driver is an essential tool. I have about 5 collected over probably over 55 years. A tool I cannot work without.
