I was thinking about buying the peice that is in the subject because I like the perc I like the mouthpiece and more importantly the price which is $89 I think. But I saw that it has 4mm thick glass and was wondering if I should be worried about the thickness also I would like to know if any of you more experienced blades had this price and was wondering if you are happy with it. Also is it very hard to clean? Sent from my SCH-R970 using Grasscity Forum mobile app
