Kwarw1, I will attempt an answer for some of your questions. First, I'm not a representative of/for Mars OneLeaf and was not sent a scope to test. Nor have I tried to get a sponsorship to sell the product for a percentage. I used my own money to purchase the Mars MT1000 back during a 4th of July sale on Amazon. I cannot answer your question on those who have warranty/repair issues and purchased from Hong Kong. I don't know what the shipping rates would be there. I also don't know of anyone who has had a warranty issue, but surely there must be some after this length of time. I purchased from Amazon because I knew I would have 30 days to send it back should it turn out to be junk even though the reviews were good, almost too good in fact. I was told by the rep. who works for Akk (their Amazon Online Store) that should I have warranty/repair work all I would have to do is send it to her and she would take care of the rest.
So, I have explained my thinking in the 30-day return to Amazon and the risk involved for $1,729 to my door. Originally, I wanted the scope as a back-up to my Super Yoter which was going out of warranty in Oct. 25. The Super Yoter is now my back-up scope. Part of my figuring was that I invested $4,500 in the Super Yoter, a very good scope, and the MT1000 was about 1/3 that price. So, I had nothing to lose provided the scope was at least decent for a 30-day test. I found it to be at least as good as the Super Yoter with more features. The LRF and Ballistics Calculator are nice additions, but I'm not likely to use them much. The warranty is only 3 years, but that was also the case when I purchased the Super Yoter for 3 times more money. Four year and five-year warranties are pretty new brought about when I-Ray entered the market.
Perhaps Mars has a different marketing strategy. They are eliminating the mark-up for those companies reselling their scopes and can sell cheaper. Are they cheaply made and inferior components? I don't know. I suspect that one of three things will happen. 1) Mars will fold if warranty becomes their "Albatross", 2) Prices will be driven downward for all the big names as they find more customers turning to a scope that is on par with theirs for 1/3 or 1/4 the price. Part of marketing strategy for the big names could be to go toward the higher niche scopes offering 1280 sensors with 10Mk to justify the higher prices, 3) the 640 class scopes will become so cheap they will completely gobble up the 384 scope market and actually be available in stores like Walmart.
I have several friends who are long time posters here on PM who have purchased the MT1000, so far none of them have written to me wishing they had not gotten this scope. Of course that could change tomorrow. Only time will tell what happens on warranty issues. I'd love to hear from someone who has actually had to go
this site through the process either with Mars in Hong Kong or Akk here in the US.
