As magic has more and more electronic tricks that are mass marketed a few problems are popping up. First one is customer support if they don’t work correctly. Usually the manufacturer doesn’t have incentive to repair the item. Sure they may replace it if you recently purchased it, but after that your main option would by buying a new one.
That’s why I like companies like ProMystic. They sell higher end products, and they will repair them. For example I’ve used their trick Inception for about four years and the screen went out on it. This is not their fault, I’ve used it in close to 1,000 shows across the USA (and North America) and over the years it’s been dropped, gotten wet, and still worked like a champ, even without the screen!
I finally had a gap in my schedule where I don’t need it and sent it in to them for repairs. For way cheaper than I thought it would cost for a screen replacement, they put a new one on it and it’ll be waiting for me when I get home in a few days.
For me having the option to have a four year old prop repaired instead of buying a new one is great! If you’ve been on the fence about getting anything from ProMystic, they are a great company and stand behind their products and help with support long after your purchase!
