For me the advantage makes easy icy windows and free cleaning performance I find also very good. No lubrication (if you never replace the wiper blades or possibly sometimes cleans by hand, smear each washer fluid).
In addition, it comes with a small spout (under the handle) that can be fixed again lacked even there.
The canister is made very valuable and I have no doubts that I could have the canister handle even unexpected in hand, how I was with another product of another company ...
I have tried a few products. From clogged nozzles by soap or smearing and streaking on the windshield insufficient sprayability or freezing at -5 degrees Celsius.
This concentrate, pure used, I have a very good cleaning performance even at - 18 degrees Celsius. Even if my discs outside when driving times wanted to freezing, the concentrate is made again for a clear view.
I use it for years now and my washer will thank me.
