I really like the compact size and retractable handle, even the stowaway feature for the hook is a nice touch. I do notice that you have to be very quick to try and get an accurate weight.  Example: trying to weight my Nemo air pad. You must have it on the hook but not hanging yet. press the button and quickly raise it up to get the weight of the item before the hold feature kicks in and stops the weighing of the item. After several attempts I got it narrowed down to 1.96 to 2.0 lbs on 6 tries. So I really kinda hate the HOLD feature! You buy a scale for the correct weight each time, there should be no difference in weight on the same item. It also should not depend on how fast you can get it on hook and into hanging position before your time runs out. Also depends on if you item is swinging about. That's why it only gets 4 stars. I do have a smaller scale DigiWeight for grams and ounces, really great product for smaller weights and very accurate. I will keep this one as it was cheap and is pretty close on weights so it will do for my needs. Just be aware of it's touchy handling, hope it gets better with use, I might just need to play with it some more. In the video I chose a small light weight empty camera bag, not so much swinging as heavier items, just so you can see it in action. A couple of photo's for size measurements. I also noticed a small speaker ?? on rear of scale by the hook storage and a on/off button in the battery compartment, not sure what it is suppose to do as mine don't work. will be asking amazon if they know....

UPDATE: From the company, the switch in the battery compartment controls the scales ability to shut off automatically. In the up position the scale must be manually turned off, in the down position it will shut itself off.
