It does the job it says, it requires a lot of material to achieve the result. I spent 2 bottles on a couch about 5 meters long, including cushions, and I wouldn't say it was enough; I didn't cover some spots well because the product ran out. Also, the vaporizer is terrible; it breaks after 10 presses

I used it on a jacket for restoration. It does the job. One bottle easily covers two jackets. Apply on dry fabric and make sure to soak it well. If the fabric is dark, after application, shake off the excess material to avoid watermarks. The sprayer broke immediately - unacceptable for a "professional" product - but if you have an old pump (e.g. from a window cleaner), you can use it just fine.

I use it on the convertible car hood! Very good result and duration, you see the water sitting in droplets on the roof without letting them penetrate the fabric, it lasts... months... depending on the quantity! But be careful on any surface it falls on... it stains and comes out very, very difficultly!
