I read this thread with interest. I've been using cobra releases for 4 years. I've had no probmems except after 10 days of very dusty conditions on an ATV, I did have to rinse the dust out of the mechanism with water to get it function more smoothly. Rather than spending the $ on more expensive models, I picked up a couple of extra releases. One is always stored in my fanny pack along with the extra arm guard and knife (this is because I know myself and "Murphy" really well). I then keep the other in the bow case, and of course the third, on my wrist! While 4 years may not be a real long time, I have been pleased with the service so far. I have played around with other releases, but did not experience any significant benefit in the let off or lack of travel, or in accuracy. Being the gear junkie I am, I still look at new releases every month or so--just haven't been able to justify it yet. Do the high end units really make any difference? Are they worth 2 to 3 times the money?
