User Review: Optimus Nova
Price Paid: $99
The pump cup is leather and you will have problems with it, which will cost you a 30 dollar extra service kit. The pump rod is a soft aluminum alloy rod, it bends if you push a little hard.
If you have any problem with the pump itself, the new pump (just the pump itself) is 50 dollars, connection hose is 15. So, so expensive it is unbelievable.
Get a stove with better built parts and decently priced.
