GJEMAX (battery tool)

Moin together, I have seen the days an advertisement of a supposedly German company (where the production or stealing I don’t know..). They make battery tools that come very close to Makita optically. Also the batteries of Makita fit there, vice versa of course also.GJEMAX Does one of you know that or maybe someone has already held the tool in hands? From the price m.M.n. very interesting, for the hobby screwdriver this should be enough. Advantage would also be, one k could use already existing Makita batteries and would not have so many different charging systems…. Or as a replacement buy the battery from them, for 6 Ah they ask a good price. I have with the company nothing on the hat and do not advertise for them, just wanted to hear if someone could share an experience. Greeting
