OPTIMUS SVEA

Stoves nowadays are the result of years of testing and adjusting by people and companies but this has needed little or no adjustment in over a century except for the cleaning needle. Simple design and easy to use really. Aspen 4T is the fuel I use. Possibly not perfect for todays ultra lightweight backpacking but nonthless a great reliable little stove to have in your arsenal.

It’s a great stove and like others have said not the easiest to use. However it’s really robust and well made. I’d recommend Coleman fuel, it works faultlessly. It burns hot and is really cool considering how old the actual design is.

Not the easiest stove to use by any means, and with modern additives to unleaded petrol it's not as easy or cheap to run as they once were. Despite that it's hard not to fall in love with shiney little stove, and it's still very economical to run if you use Aspen 4 stroke fuel (available from larger garden centres and lawnmower specialists).
Not likely to replace my Coleman Sportster as the "permanently in the car" stove, or my Primus Omnifuel as the "campfire backup". Instead it holds the esteemed position of "canoe carry". This is because space is more of a premium than weight (no titanium here), and it's just a joy to look at and tinker with on the riverbank.

Only used it twice, but very impressed with it. Good quality nice and compact little stove.

Quality Optimus / SVEA product.
I had read some negative comments about buying new, compared to second hand originals but decided to buy new anyway as I already have the Optimus Omni fuel that I love and second hand caries risk of previous damage.
The finish and quality of the new 123 is excellent, works perfectly, continuing to uphold its excellent well earned reputation. Highly recommend buying this product. the R function of self cleaning makes it even better!
