This has been such a great experience. Big thank you to Stefan & team for doing such a great job on my order! I love all the tiny details right down to the bolt holes, oil galleys, and coolant jackets. Not to mention the awesome rings themselves which have super precise engraving! Bravo!

I purchased a couple of these for myself and my sons for their cars. They were a big hit at Christmas and, having been in use for several weeks, they are holding up well to daily use.

The pros: well-built; thick enough that they don't bend in your pocket during use; all the car nerds who see them, love them; large enough (and strong enough) that you can reach into a backpack or pocket and find your keyring easily and use it to pull your keys free without bending or damaging them.
Cons: basically the only negative to these is that they are a little big (especially the I-6) so having them in your pants pocket can be a little uncomfortable at times.

Quick delivery, perfect quality. Nice add-on to my keys :)

All in title, it's a good quality device very nice to put on my volvo keys!

This is a fantastic addition to my keychain that really sets it off. Quality is great, and I've already gotten many positive comments about them. It also makes the set unique when I drop it off for maintenance.

Excellent quality.

Mini headgasket made from very high standards and a quality product. It was a very good purchase.

It was exactly what I expected and was constructed very nicely. Absolutely would recommend!

I bought this as a gift for my son, who rebuilt a VR6 recently and has had to explain a dozen times how the engine is structured. The replica head-gasket is a conversation starter and helps get the ideas across. Beautifully made. I recommend this product.

Good size, nice feel, amazing machining, overall 5 *****/5

IT is like Pandora for car nerds.

Impressive quality and looks very good.

What a quality piece of work . Great surprise how quick I got it

Hab diese Anhänger gesehen und fand sie mega cool. Hab mir dann den M54-Anhänger bestellt und war positiv überrascht. Paket war nach nur wenigen Werktagen da und das Produkt sieht genauso aus, wie auf den Bildern - Material sieht hochwertig aus, gut gefertigt, nicht scharfkantig oder sonst etwas
Gefällt mir sehr gut und macht sich gut am Schlüssel

It was just like the picture - can’t do anything but recommend your products. Quality was good, too!
It was a Christmas gift for my car loving husband and he loved it so much 🥰

Thank you for this!
