Review on USB Rechargeable Heated Body Warmer Vest For Men - ZLTFashion Electric Jacket For Winter by Joshua Gallegos

Getting older and feeling the cold more than I care to admit. Got one of these hoping to help keep the upper body warm while walking behind a snowblower. Arrived quickly and was packaged nice enough. Plugged the included battery in right away to prepare for upcoming cold weather. Well said cold weather arrived a few days later; plugged the battery in.and it's dead. Did not hold a charge, even for a few days. No worries, uses a standard USB, so plugged another power brick.Seamed to work fine at first, but noticed after 20 minutes or so that it wasn't "warm" anymore. Finished with outside chores anyway, so didn't check the vest till I got inside. Thought maybe it turns off after a fixed time? Nope, pushing the power button did nothing. Unplugged and replugged the battery to check the connection; vest started up fine, but cut out after a few seconds. Repeated with the plug and saw that jiggling the wire (a.k.a. normal wear and use) caused the vest to loose power. Didn't matter what power source I used (by this time the included battery was fully charged), if the connecting wire moved even a little bit it cut out.Returned the original to ebay for a replacement, which arrived fairly quickly, but that one had the same issues. Works for a bit when a power source is plugged in via the USB, but cuts out after a few seconds or minutes depending on how much activity you're conducting. Not much use for outdoor activities. So am returning the replacement as well.Oh, and the zipper is "left handed" I suppose? That is the pull is on the left side, opposite of where zippers are normally set in the Americas. Guess the intended market is Europe or Asia. Not a biggie, but just another annoyance with the product.
