Para calcular a classificação geral de estrelas e a análise percentual por estrela, não usamos uma média simples. Em vez disso, nosso sistema considera coisas como se uma avaliação é recente e se o avaliador comprou o item na Amazon. Ele também analisa avaliações para verificar a confiabilidade.
The fist pump lasted about a year. I tried to thoroughly clean it, but it sticks, and did not allow pressure to fully build up. So I bought a second one, and just replaced the cap on the second MSR bottle. If one fails, I will use the other, and order the back up once again. It lasting only a year is not the best longevity, but I used it frequently.
The newest version of the standard MSR pump boasts the most robust construction yet. Earlier models had major issues with the pump rod retaining tabs snapping off. This new design uses a twist system to remove the plunger from the tube. I picked this up to replace an older gray pump that came with a used whisperlite i picked up. It worked fine. The only gripe i have is that MSR chose to replace the easily obtainable o-ring seal on the earlier models with a proprietary seal/grip ring on this current model. It's not a big gripe, but if you need to replace it you need to go to their maintenance kit and not just the hardware store like before.
This replacement part seems to work ok. It doesn't look as sturdy as the original. I lost that in a shipment when I moved. Fuel does leak out of the pump handle when hiking so I had to keep it in a zip lock bag. I think my next stove will be a different design.
Pump works good and hold preasure for long periods of time .I like the older model better though. The flow control is very touchy and on this newer one where the old model had a round knob much like your stove at home .
