Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.080". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Works with Mac!
Style: 34" WQHD Curved 100Hz USB-C Docking
This monitor is great. I was suprised on how light it was, as I have a large Asus monitor that is very heavy. I am very happy with quality and it works great with a Mac.

Just a great monitor
Style: 34" WQHD Curved 100Hz USB-C Docking
What a difference. I purchased this screen to replace an older screen. I knew I would see some differences as the screen was a larger size. What I did not expect was the picture quality. It is exceptional. The colors appear to be accurate. Based on the build quality I expect it to be very durable. It has been very capable of running my games. This has been a great purchase.

Didn’t power on, still waiting. . .
Style: 34" WQHD Curved 100Hz USB-C Docking
I received this brand new monitor. It would not power on Amazon did not have any more in stock so it was sent directly to the manufacturer for repair. They have had it for two weeks and are going to have it for another one to two weeks before shipping it back to me and hopefully I’ll actually get to try it out I really hope it’s worth it in the end! Seriously frustrating that a brand new monitor would not even turn on and it’s gonna be at least a month before I even get to try it.

Meh....
Style: 34" WQHD Curved 100Hz USB-C Docking
Milktoast stats--right down the [lower] middle of the line. 1ms reponse time, mediocre 100Hz max refresh, and NO FreeSync support. Hardly expensive, it still is quite a bit more than other monitors with MUCH better specs, but less brand name recognition. I think the only reason it is so expensive is the white treatment. The VESA mount in the back did not fit my VESA plate. One side of the plate sat up on a small ridge of plastic. Not a showstopper, but hardly ideal--or necessary. The bezel (or rather, the DEAD PANEL SPACE between the bezel and the displayable area of the panel) is HUGE. Like 1/4" on the sides, and 1/8" on the top/bottom. If you're going to make a thin bezel, then make an edge to edge display. Otherwise, just give me a frame so that my image displays edge to edge. To me, it looks like the old CRT monitors from the 90s... YECK!
