Worth it!
Color: orange
It’s so cute and really really fluffy. I got the orange one and it sheds a lot but if you brush it out really good with a really good brush you will have little to no shed at all. Also it’s a little to fluffy because I can barely see my dashboard so that’s kinda an issue but overall it’s cute and I get complements all the time.

Worth the buy
Color: Yellow, Color: Yellow
First I honestly only wanted the steering wheel cover but couldn't find it for sale that way. It comes in sealed bag. The pieces are flat and bunched when taken out. I had a dog brush that I use to keep my fluffy slippers from getting matted and used it to fluff the pieces out. yes they shedded while brushing but not too much. The texture of the smaller two pieces were soft the steering wheel was soft also but had some spots that felt slightly rough. The piece for the brake slid on easily. The piece for the gear shift fit but was pressing against the gear shift button on the left side which kept my car from cutting off so I had to "modify" the piece. Steering wheel piece does still shed slightly but not enough to bother me. Over all happy with purchase yellow was vibrant and stands out. Would recommend.
