Angle grinder belt sander attachment (Sanding Belt Adapter Head M10/M14)

Hey lads i was cruising Aliexpress and found an angle grinder attachment. The attachment is for a belt sander it basically converts your angle grinder into a mini belt sander. I am not sure of the quality but its fairly interesting. Apparently its made from aluminum but i do see some plastic on it.

The belts are a small size but it might be a cheap option for some one who only does casual sanding or needs a narrow head on a sander. The narrow head will help get into tight spots.

First time i have seen one of these for sale but i have seen the DIY builds on YouTube.

This is the link other seller may also sell it i have not checked.

The price is 20USD so not super cheap but not to bad i guess, A belt sander will cost more.

Any one got one?
