Another name of the same fraud is Engine DIY
This company (enginemaker) and Engine DIY (enginediy dot com, and enginediyshop dot com) are one and the same scam-business. If you order from Engine DIY, the tracking link takes you to Enginemaker site, i.e., to Extremelife. Also, extremelife.shop is the operator of the emails that Engine DIY support are using. Instead of an engine kit they send you a simple plastic jewlery (for proof of delivery). The funny thing is, if you ask them, they warn you of the enginemaker site (which is already known as a scam) and urge you to buy only from Engine DIY. As said, they are one and the same business.
