As to whether they are 'worth' it, you'll get John saying his is, to him. You might get me, saying I think they're worth it, comparatively. And Del over there, he thinks his is better than brands X, Y, OR Z, for that matter. None of which means squat. The ONLY way to find out if they're worth it, to YOU, is to try one, and make your own determination as to whether it meets your needs, and if the price/performance ratio is fair. And you have to factor in budget. If your department is buying it for you, or you're getting a military/police discount, that's one thing. If you have money to buy one just to test against a bunch of other stuff you can afford, that's something else. If you have to save, or scratch, to afford one, that's a whole OTHER thing. And, unless you're in that 2ish% that will use an RMJ, or any other tool, to destruction, there are other less expensive options that will perform just as well in 99.9% of day-to-day, or emergency, use.
