I've had a chance to spend a few days cooking with my Jetboil Genesis and thought I would post a few thoughts. Overall, I really like the stove. It's very compact, has excellent burner control, and overall seems to be a robust design that will hold up well over time. It's easy to clean and cooks some great meals. Also, while others thought the wind screen was a bit cheesy, I actually like it. It clips into the stove and does a good job keeping the burners protected in moderate wind.
The downsides are a) price and b) packaging. I think at $350 (or $240 for just the stove) it's a bit expensive. It's not unreasonable for what you get, but I would be more enthusiastic about it at $300. I think if you have a 20% off coupon like I did, it's a great value.
The other issue is that there seems to be some issues with the pot durability when the stove is nested inside. My first unit showed up with dents in the bottom where the feet of the stove were touching. The stove was still usable, but for $350 I didn't find any dents to be acceptable. I called REI (where I purchased it) and they shipped me out a replacement unit. However, it had the same dents in the bottom of the pot. I called up Jetboil (or more specifically Johnson Outdoors) and talked with customer service. The woman on the phone knew what the issue was before I was able to say it. She told me that it's not a design issue, but a "packaging" issue. I don't know if she meant the box that the stoves are shipped in or specifically how it nests inside the pot.
Regardless, they overnighted me a new 5L pot. I really can't complain with that level of service. In order to prevent my new pot from getting damaged, I went to the arts and crafts store and found a 9" circular piece of MDF that was sold as a "decorative chalkboard" for $2. I also bought some thin foam, but the mdf sits perfectly down in the bottom and did a good job protecting the pot on my recent trip to Big Bend. It's also easier to clean off if needed than foam. I'd be curious to see if Jetboil modifies anything to prevent this from happening on other units in the future.
