- low quality and rough texture of the body plastic;
- custom logos and stickers;
- lack of serial numbers and equipment of engines with simplified non-compensating carburetors;
- the presence of spark plugs with calm symbols, the production of which the company is not engaged in.

Should you buy a fake for which there are no spare parts? Is it worth buying a fake, getting it out of which I’m not sure whether it will start this time or not? Is it worth buying a fake in order to go very soon and choose a new chainsaw?
