I have used this set of pots on a few backpacking trips. No complaints about the weight, or size. I can fit my Whisperlite stove inside the small pot.
The pots discolor a bit after use over a flame.
Although the pots and lids fit together quite well in the supplied mesh bag, it is handy to have a rubber band or something to keep the lids closed tight to stop any rattling.

Very good but a little on the flimsy side. I guess going ultra light has its down side such as thinner walls to save weight...

Light, durable, and packs down small. Couldn't ask for much more in a cookset. The pans have fold out handles that lock in place and are capable of holding up the heartiest of meals. They are designed to be able to nest a Snow Peak large fuel canister and a Snow Peak stove inside of them. Remember to have something handy to grip them with though as the handles can become quite hot.

I purchased this set for solo use as well as family camping. The capacity of the set is more than adequate for our family of three.
For solo use either of the two pot/lid combos will suffice. Heating is fast and even. I prefer the integral handles over separate pot holders; they stay cool enough to hold with bare hands and
they're a lot more convenient, too. Snow Peak makes top grade gear. Definitely recommended!

This set compliments the 450 mug and Trek 700 mug/pot I already owned. All four nest together nicely for a complete set that can be used as a whole set or segmented to suit your needs. In order to increase the heating efficiency, I paint the bottom of the pots with black stove paint. Using a Trangia alcohol stove, I can boil 1 liter of water in calm conditions just less than 10 minutes. Not as efficient as some of my other pots, but I believe that is due to the narrower diameter and taller height of the pots. The height is harder to keep hot when convectional currents cool the pot. For having the versatility of all four mugs / pots, this system is a really nice compliment to my collection.

Decent set for a solo packer. I agree with dtab - the short pot burns eggs badly, but that could be because I never grease the pan. Bring a brillo pad to scrub off the previous meals for sure. The smaller pan works fantastic as a bowl. Large pot stores fuel canisters nicely. Works great with my GigaPower stove.

I picked these up along with my solo set. I've cooked for five people with this set. They look small but that is due to the fact that they aren't wide like most other pots. They are tall instead. I'm pretty sure that the shape is due to their stove designs. The Snow Peak stoves are quite small and only heat a small area.
The one point that I'm not a fan of, but I knew when I bought them, is that the frying pans don't work at all. Titanium doesn't channel or distribute heat well so if you want burnt eggs with runny whites give it a shot. Use the frying pans as bowl/plates.

The best feature about the Snow Peak Cookset is the design. All of the pieces nest together, and the Gigapower Stove and fuel canister also fit inside the cookset.

I initially used my cookset with an alcohol stove and did experience some discoloration and soot, but the product warns that this might happen. I soaked the set in warm water overnight and was able to clean everything to my satisfaction. Then, the titanium Giga stove went on sale, and that thing is awesome! Everything works together seamlessly.
