Primus Eta Express is Awesome!
I bought this stove for motorcycle camping, and it performed outstandingly! Mainly, I use it for boiling water for coffee in the morning; it boiled water so quickly that it was difficult to get the cups and Starbucks instant coffee set up without having to shut the stove off first.
The piezo starter worked flawlessly, and my friends commented on the great design and function. This became the only stove we used on our last trip.
To conclude, this stove is perfect for my needs during motorcycle camping, and I cannot yet think of anything to add to make it any better.
