Review on Stainless Diameter Thickness Material Modified by Walter Day

I bought several of these and it was a second chance. When I got the size 90 the only thing that was correct in the description was 90 degrees and 76mm (or just under 3 inches). Simple math says 1.2mm is 0.047 inch, which is about 17 gauge sheet metal. I work with sheet metal every day, so I used my gauge controller (which only goes up to 19g) and popped it into the 17g, 18g, and 19g slots, and it's in both cases sloppy. Compared to about 20g of crowbars I, and guess what, your Uncle Bobs. The 1.2mm THICK I received was neither thick nor 1.2mm at all. It was a 20 gram tube. very thin. For my application (turbo hot side) it is too thin. Luckily I should be able to get other whistles working along with another whistle I bought instead.
