Man, what a great bunch of comments there are in this thread. I think people like me will be Arsenal customers when the word gets out, people with physical limitations due to health or aging or both, or people also like me who got badly frostbitten hands and feet earlier in life and experiences severe pain being out in the cold for more than a very few minutes. Arsenal reopens a photography opportunity for me that would be long gone without it. I think they have a smart product that can be an advantage to me now, and also think they have a smart business model. They're heavily funded up front, have created a good demand without speculative manufacturing, get paid up front and don't produce their product until they're paid for, have no warehousing overhead, have the best, most feature rich of selectable features of all the competition in their class, have a waiting list, and only produce what has been pre-sold. They might sell more if they weren't doing it this way but they're assured of not losing money due to too much overhead and lack of sales, no small matter of concern to a new startup business. On DPReview there are some of the same kind of comments as are in this thread but generally I can't find any evidence that the company is in trouble and they do have a waiting list of people who have paid in advance. Looks like one hell of a deal to me, a lifetime entrepreneur. Incidentally, looks like they started shipping mid to late summer of 2018 and I'm unable to google up very much negative about the product or the company. Of course, there'll always be some. The company has an extensive Facebook page and there are several Facebook "groups" dedicated to it.
Although not leaving much to the imagination, Arsenal allows me to drive a few minutes, hours even, up into the Rockies, in sub-freezing, often below zero, weather, snow everywhere, sit in my warm car, heater running, with my camera on a 360 degree remote control motorized tripod head with the tripod stuck out in several feet of snow, avoiding the pain associated with frostbite, arthritis, and other aches and pains and the ravages of being nearly a fifty year diabetic, and sitting in a warm place operating every desired aspect of my camera manually from up to 100 feet away, and more, on my tablet or phone, just as though I had the camera in my hands, shooting nature shots, landscapes, panos, wildlife at watering holes, and way more, and have the shots partially post processed, hdr, focus stacked, etc., into images ready for my final touch, on the fly. That allows me to spend less time sitting at my computer, which is not only not good for me, but also not nearly as pleasant as sitting in my car in the mountains on a beautiful crisp sunshiny day doing something I love and being rewarded with some very visually pleasant souvenirs while enjoying all the creature comforts of home.
I can stay as long as I choose with a full tank of gas. I have room with no strain for all the extra equipment I want to take along, can listen to a little smooth jazz, with ready access to a thermos of coffee, an ice chest with food and water, no problem. When ready, I pull my camera in my vehicle and head home. I see no merit in sacrificing those experiences just like I see absolutely no merit in the argument against using Arsenal that I see in most of the comments in this thread just so I can lay claim to all the empty unjustifiable reasons not to do it since it gives me extra-human capability at 82 that I wouldn't have had at 30 and it opens up a whole different genre of photography for me, i.e., beautiful snow covered winter scenes and magnificent critters like deer, elk, moose, birds, etc. With little to lose and only a pleasant time to gain, it would to seem to me to beat the hell out of being in a nursing home in Florida sitting around blowing smoke up people's butt about what a great photographer I was back when because I only ever shot in manual and never touched a gadget like Arsenal and topping it off by telling about all the good times I had hiking back in them woods while channeling Ansel Adams. Choose your own poison, boys and girls. I just thought I'd toss in a little representation for those of us who have no stodgy reason not to try something new. Happy shooting everyone!
