I have a Snow Joe snowblower and my experience is the opposite. Had it about 7 years now, a part broke in shipping and they replaced it no questions for free. After that, it has worked just fine for those 7 or so years.I’m here to advise against the Snow Joe/Sun Joe brand. The snow blower is weak, batteries last only 30 minutes, and the machine has been replaced 3 times under warranty. They did stand by the warranty but I’m sure when it expires it will soon end up the landfill.
... as long as you have reasonable expectations about what a single-stage snowblower accomplishes. 8+ inches of wet, heavy snow, it can't handle. So either have to do it in 2 parts, or call a plow.
