I really like Gyeon Quick View and have been using it on both garage queens and daily drivers since it was released.
Stated longevity for Quick View is said to be up to 6 months. I have seen it last 2 months on a daily driver with minimal maintenance and heavy use of the wipers. On the flip side, I still have it performing on my personal daily driver after 10 months.
How long it lasts will come down to preparation, maintenance, environmental and storage conditions. For context, although garaged overnight, the daily driver is often parked in the sun all day long and exposed to all conditions. I also don't overuse or dry-wipe the wind shield. 10 months and still performing is pretty decent for a product with a stated 6-month durability.
I clay the glass first before a wipe down with Eraser or Prep.
The big selling point of Quick View is the integrated felt applicator, making it very simply to use.
The cap on my bottle actually welded itself in place, meaning I need to apply it to a separate microfiber applicator. Either way, wipe the product on in circular motions and leave it to cure for 15-20 minutes.
For the residue removal, soak a microfiber towel in water and wring it out until just damp. Use this to wipe away the residue. I then follow this up with my normal glass cleaning process to leave a clear, streak free finish (the glass cleaner
won't strip the product by the way).
From then onwards, I simply use some of my chosen drying aid to maintain it. If you don't use a drying aid, then just apply something like Bead Maker every month or two. And even if you don't do either of those things, re-applying Quick View is so dam easy anyway.
