Bought the Tesla Tire Repair Kit in December (a couple months after receiving our Y). Hit a road hazard in Wyoming on a long trip. Out in the middle of nowhere. Was losing pressure so pulled over into a deserted off ramp 25 miles from the nearest town. Pulled out our previously unused Tesla Tire Repair Kit. The air pump on this unit worked, but the sealer did NOT WORK. No sealer came out of the unit. We followed the instructions (simple). When that did not work we tried every variation of power cycling, button sequencing, etc for 10 minutes. It is difficult to describe the degree of frustration when you are miles from help in 95 degree heat. When we needed this unit to work it FAILED. I cannot recommend this unit. Thankfully I carry a traditional rope style repair kit. That allowed us to get to the SLC Tesla shop (150 miles). They fixed everything the next morning and we were on our way.
