My wife's Hyundai Kona has the same setup; a small compressor and a can of sealant.
I kind of like the idea, since even someone with limited arm strength can use it, whereas some people cannot put enough force on a lug wrench.
But, it's limited in it's utility, since a tire that has sidewall damage would not be able to be repaired.
Sidewall....funny you should say that...
Daughter calls and says she has a flat about 3 miles from home late Friday night. Stupid little Fiat she had. No spare and cut in inside sidewall so I didn't even see it and wasted the sealant crap. OK, now what? Had to have the car towed to my house. Sat morning I try removing the wheel. Frozen solid. All lugs off and zero movement. I beat the crap out of it with a rubber and dead hit mallet and still nothing. Spray everywhere with WD40 and 2 hours later it pops free. Call around for the tire, everyone says Special Order will have it on Monday, EVEN THE DEALER. Monday AFTERNOON I get a call that the tire is in so I throw the wheel in my car and get the new tire installed. Then back to my house and put on the wheel with new tire.
She had no use of her car from Friday night until Monday late afternoon BECAUSE OF A FLAT TIRE ! ! ! ! ! ! ! !
