I also had a bad experience originally from a cheap import from Harbor Freight. I think i only paid 10 bucks. Now, I always check the reviews first from reputable websites like Home Depot and others before looking for a deal on a site like this. If these are the Nature Power branded ones, they will be fine as that is the company that usually charges a bit more for their products but the 2 different models I have work great after a couple of years.
