If the 2 year warranty is true, that would probably make these cameras a slam dunk for many folks. That would take much of the cost risk out of a low end cam.
With what I have seen with almost all of these cameras, not specifically "Boly" cameras, a two year warranty is a self inflicted business death sentence!
I don't think it is necessarily worse from a business standpoint. If you buy high enough volumes from the factory and get your per-unit cost low enough, you can probably swap 3 cameras or more for each failure. With these small cameras, shipping cost is not as bad as with the larger units. If you sell cameras with QC issues and have a short warranty like stealth had, you get a reputation like stealth has. Pretty soon, your sales drop and you need to up your warranty to stay in the game.
If the cost you are paying on a per-unit basis is low enough compared to the competition, moving to a 2-year warranty should steal a lot of sales from the competition at the low end where QC is a real issue. This could force your competition to go to a 2-year warranty. Given you both have similar failure rates, the larger units of the competition are going to burden both them and the consumer more than it will you.
I think this is a great strategy. I'm presuming a company as large and diverse as Bushnell can even take a loss on one product line long enough to drive some competition out of business. With their volumes, their per-unit cost will likely be lower than the competition.
I also think this is good for the consumer. If it is effective, I expect it will drive higher end camera companies like BEC and Reconyx to go to longer warranties. This will cost them little since they have low failure rates, by comparison. However, as a consumer, I like having a longer warranty even if I don't need to use it. In fact, if I were BEC or Reconyx, I'd consider increasing warranties even longer to help differentiate my products from the low end cameras.
