Not a wedding "carpet". In bike parks, I use it as a protection to be able to step on a clean surface when changing shoes etc. I wouldn't use anything as a permanent platform. Goes into a small roll, but is also really wrinkled.
I haven't used the worst carpet yet, but it seems quite competent. Compact, doesn't weigh too much in a backpack if you take it with you. I bought this initially if the bike needs to be serviced inside, e.g. in winter. But due to its lightness, it can also be taken with you on trips, when you can use it as a seat base, etc.
Good floor protection on the bike balcony for dredging.
A good and cheap maintenance mat if you maintain a bike on the parquet floor in the living room, for example. Easy to clean.
A handy protective mat that goes into a small space when temporarily doing bike maintenance work and does not want to mess up places. One star left when the material is such that it is difficult to spread just below.
Very good. Still works even a couple of times a week on the carpet rolled with studded tires
