I find its to be a good fuel bottle. I use it to bring shellite with me for my stove. It does a good job I would recommend it. Quality all round. It doesn't leak at all even in hot conditions in my back pack.
Lightweight without any risk of leakage. Well constructed. I like the pourer which gives you a good amount of control over how much fuel reaches the spirit burner. Generally the bottle looks"professional" and I consider it an essential accessory, even if for safety reasons.
