Hello, I used this material on a multi-tool brand AEG (Omnipro 300). Everything fits well with the kit provided by AEG (no need to buy a universal adapter). Small flat for the mini triangle sanding pad (it has not even half a component for small angles of "semi component"), the plastic part was breath too quickly! Too bad it was handy little sanding triangle (AEG should provide an office!). The triangular plate is larger (96 * 96, I think) that provides original AEG (85 * 85). This is convenient because it can receive all the cheapest market abrasives. I found it good (although those of AEG and Fein are costal). The triangular abrasive large enough and keep doing the job. I have not had the opportunity to test other accessories. The storage box is a plus, as well as the leaflet inside the box on the "heads". Still I recommend this product for quality / price! This allowed me to grind my shutters for less! Amazon thank you.
