They work and quite well at that. In my opinion the E 2000 was probably the first in the next generation of stabilizers that really dampened noise and vibration on many of the single cam bows that were prominent at the time of its release. I used both styles exclusively or in combination with other Sims products for several years. I have only changed recently due to specific weight and balance issues with some of my new bows.

The problem nowadays though is that there is so many stabilizers on the market that it is difficult to get a handle on what might work and what might not. Also, because of the large number of choices available you typically do not see quite the following for one particular model or another that you once did...though those Stealth guys are sure vocal at times.
