Question about Doppler Rollsockel Easy Move Switch

great on hard, smooth surfaces, no on grass

It can't be moved on the lawn, it's too heavy and the wheels are too small! It also gets stuck on uneven slabs.

No problem on the terrace. Rolls perfectly well... I've never tried it on grass, but given the weight I don't think it would be suitable.

I don't know, I haven't tried it, I think less so

Yes it can be moved easily but probably not on grass

No, unfortunately not (in the grass) because it is quite heavy.

In the grass, it's probably not made for that

Yes and no. It's easy to move around, but I don't think it can be moved on grass, as the rollers are quite small and the thing is quite heavy.
