- Folding handle and a mesh bag
- Hard-anodised aluminium, no coating to wear off
Weaknesses
- Only for boiling water: it isn't made for cooking (ReviewOutdoorGear)
- Plastic handle grip and knob, so keep it off an open fire (ReviewOutdoorGear)

- Optimus's international site still lists it
- Shops give different weights: 146 g to 164 g (Optimus gives 153 g)
