At present, there are many counterfeits of BOSCH in the market, and the prices are generally between 1 and 16. Their place of origin describes that they are made in Malaysia, and I don't know why the prices in Malaysia are so low. If this is the case, the China government may also sue Malaysia for dumping, and domestic power tool manufacturers can close down long ago. It is true that the production place of BOSCH is indeed Malaysia, and many domestic goods are also Malaysia, but if you are discerning, it is easy to see through that they are selling fakes or euphemistically called: knockoffs. Just look at their product parameter trademark: the target is 22 V ~ 5 Hz 2.8A91W I wonder if this kind of seller has studied physics, 22V*2.8A=616W, and their target is 91W. Think about BOSCH. If so, it's not called BOSCH. The correct logo of authentic BOSCH products is: 22 V ~ 5 Hz 2.8A6 W. Instructions, warranty cards, after-sales service contact numbers, etc. should be available. Of course, the fake BOSCH will be greatly discounted in terms of related packaging and quality. As for the quality, it is false, and the quality of the product can't be guaranteed. Even if it is a five-year warranty and a ten-year commitment, you are waiting to pay the maintenance freight and the spare parts fee. There are many false questions, so I won't cite them here.
