The watch strap is very soft and comfortable, but instead of a strap loop to hold the belt on the outside it has a gap where you have to insert your other end of the belt which gives the feeling of a ring and the end part doesnt hang outside (please refer the photo). Weight limits are included to let you know what they can hold. I work in the well pump industry. The zippers work well and they are an excellent design feature for taking them on and off quickly. but DID NOT CHARGE! A few minor suggestions when putting up into a suitable wood background:- you probably don?t to waste time measuring out with the paper template provided as you can mark through the bike rack itself- you will need to drill pilot holes as the screws provided are chunky and won?t go straight into the wood- the red plastic sections are a little fiddly to get used to as they weren?t clear on the instructions, at least to me. The pump it comes with isn?t necessary. Before buying this large quantityI was not sure to buy itBecause if this is not a good qualitythen waisted money. As per the size, it is true to fit. The more you have on, the longer it will take to achieve a full charge.
