You don’t find out it doesn’t work until its the day you need it to work most. Then you have to wait for support. I just try to find solutions on my own. As the support doesn’t really offer much support. So teh frustration is because when you need it, its not reliable. I shouldn’t have to warm the snowblwoer module so the chute thaws. Its a snowblower. It should work in the weather its claimed to work in. Still a fantastic machine when it works. Which it does when we thaw the chute. Once its diong its thing it has no real serious issues. But getting it working after sitting.. well that’s a gamble you risk dealing with after each snowstorm.
