Nylon Mungo Easi-Drivers any good?

[-Paul-]

I've always used metal easy-drivers, but noticed how cheap the Nylon Mungo Easi-Drivers are on screwfix per 1000 http://www.screwfix.com/prods/64161/Fixings/Cavity-Fixings/Mungo-Easi-Drivers-Nylon-32mm-Pack-of-100

Are they an ok brand?, is there much difference in strength over the metal ones?

Thanks

I tried a small pack of them to test. They seem to work ok though can be a bit brittle.

I don't know how authoritative these videos are, but this guy rates the Nylon ones at able to hold 30lb and the metal ones at 50lb.

I think I'll maybe carry on using the metal ones for shelving, but the nylon ones for items which wont have much load on them.
