I have used both. Both are good. Comprod is very proud of their products.
The two sets of comprods have only been in a year or two so hard to tell long term reliability, I have about 8 sets of those telewave units in for about 12 years with zero problems. I also have about 14 sets of sinclair Res-locks in for nearly 20 years with minimal problems. All of them have zero desense and to be honest if I had to tell the difference by testing I dont think I could.
If your interested in a very lightly used set of telewave cans let me know, I have a couple sets that were only installed for testing purposes and never seen a mtn top.
