These are similar to the Bach Artisan spring in shape, although the material is slightly different. Believe it or not, I feel this material adds to the resonance of the horn compared to the typical aluminum (silver colored) springs. The Artisan springs also achieve this but are very hard to find and only come in one size. I am VERY glad to have found these and would definitely buy them again.

The springs are working, the originals replaced with VSO2. They appear to be "stronger" than the originals on my Kanstul 1530 cornet.
These springs have made vast improvements on my trumpets. Nothing else can be said!
I already left a previous review for these springs, but just want to add that I picked up yet another set for my Bach 37. I replaced the original aluminum valve stems with brass ones, and the VS02 springs balance everything out very nicely. No bounce. Original springs on this horn were shot, and OEM replacement springs just weren't cutting it. Pick up a set of these for all of your horns! I did.
I purchased a set of the VS12 for my Selmer K-Mod and for my Martin Committee, and then had to get a 3rd set for my Holton Stratodyne cornet. Got rid of the bounce I was having in the valves on all 3 horns, which likely all had their original tired old springs. Made a huge difference. Highly recommended! (I ordered the VS02, and they sent me the VS12, but are actually the same thing with different package.)
Excellent, and fast shipping.
It works well with my Holton Revelation 48 trumpet. I like the quality of the product. Thanks!
Just enough extra tension, but not hard to press. Quicker return to open. Makes a nice difference esp. when doing "Clarke drills," etc. Not for everyone, but worth a try in my book.
They seem like pretty good valve springs. I am not convinced these "High Speed" valve springs are any faster than other valve springs, but they do seem to be of high quality and have a nice "feel" to them. Good product.
