I bought the gear lever and handbrake bubble set, all buttons fit almost perfectly. The four stars are because the gear lever bubble does not have a zipper like in the photo, but a rubber band, which makes it a bit difficult to install as the lever in Opel Astra G does not come out easily and personally I had to tear the bubble a little. If the gear lever bubble had a zipper, it would have a perfect fit (I have bought a similar gear lever bubble with a zipper). As for the handbrake bubble, it fit perfectly. As for the quality, time will tell
