I just logged in to ask the same question. I went the cheap rout and bought a couple of EZ kits for my car a couple of months ago. I just ordered my glass a couple of days ago and the guy told me that they would not hold up because my glass is too big and heavy. Now I get to return them and pay a 20% restock fee. So much for saving a few bucks. I will look into some of the brands you guys suggested.
thanks
