Review: Great Product, does what it says - This is easy to apply, works similar to rainex, cant review longevity yet however its been on a month+ and its still the same as the day it. Get a very tiny amount of wiper judder in mild rain but its next to nothing, its not enough to bother me thats for sure. *Update* the product lasts about 9 months, i applied in August 2024 and come Apr/May it was starting to fade, the vehicle does about 5k a year so not high mileage. It was applied after using cerium oxide to polish the glass, clay bar then Iso alc to clean any residue so i dont believe any other type of application procedure would increase longevity.

### ⭐⭐⭐⭐ Wiper juddering
*by W***R on 5 December 2024*

In my opinion the product itself is great but there is one flaw that comes with it. There is lots of wiper juddernes after 4 ish weeks. I tried to re apply the product on the wipers the juddernes gone away for 1 day and came back. The product performs great on the highway and helps alot at night when driving in the rain. Also keeps your windscreen clean and it's easy to clean of. In conclusion I would reccomend the product but I would be aware of the wiper juddering as it can get annoying
