I purchased the 18" Anco Winter blade because I needed a good wiper for my primary winter vehicle a 1994 Ford Bronco 4x4.  What's the use of 4 wheels in the snow if you can't see where you're going?  These blades proved to be excellent!  I was amazed, especially since I was reluctant to purchase these seeing as the "normal" anco blades haven't held up for me very well over the years.  I put them on right before either the first snowfall of the year or before it gets really cold.  No sense busting your knuckles, especially when its 0 degrees outside when the pain seems to multiply 10 fold.  lol.  I bought a set end of 2010, took them off when the weather improved and switched them to my "summer blades" and I just recently put the same set of winter blades from last year back on.  Tested them out, still work like new!  What is nice about these blades is the fact that they do not stiffen up with the extreme cold and they do not form ice on them when you use your windshield washer like the metal ones do.  We all know its a pain and dangerous bashing your wipers against your windshield just to get them working right again.  Which these seem to eliminate.  I would recommend them to anyone who has to drive in adverse cold weather conditions.Tips:Put them on before it gets cold/snowy.  No sense waiting until last minute and suffering!If they still work, SAVE THEM!  Use them only when needed through the winter season.  I stored mine in the garage through the summer.If you save them, wipe them down with a towel or cloth soaked in rubbing alcohol before putting them on.  This cleans off road grime and restores them to maximum performance.  A lot of reviewers complained about streaks, etc.  Unless the blade is physically damaged this can be fixed by doing so.If for whatever reason in extreme cold they do freeze, don't bang them and definitely do not try picking or scraping the ice off of them.  This will damage them for sure.  What I do is take some prestone windshield deicer and carefully spray them down a little.  Works wonders, just watch your paint.
