I have never heard of MSR Arms before but came across them several times past year or so, I had a quick chat with the customer service about some technical topics and they were knowledgeable enough to not only answer my questions but also to have a good conversation. I believe the communication and connection is there, not only that but products they carry are great quality. I am only disappointed on one thing, which is super delayed shipping time. My order took more then 10 days to arrive to me but I will not rule out the fact that while the ongoing COVID19 is taking place many companies were short staffed and resulted in delayed production. So I will not point fingers and say their shipping sucks, it could be better tho.
