Some colors make it impossible to read the clock hands against the background.I liked the idea of these watches. I do like the variation of colors; I chose the blues. I do enjoy not needing to wear a watch on my wrist. I wear it on my lanyard and do vital signs quickly. The watches are accurate; I checked them with my phone stop watch. They’re quiet also. You can wipe them down easily. I use them for my students who can’t afford a watch; I let them borrow one. However, it would have been nice if all 5 worked upon arrival. 4 of the 5 worked. (I had already thrown all the packaging away for the other 4..the 1 that didn’t work was the last one I opened!) Which makes me wonder how long are these going to last. I’m hoping I’ll get some mileage out of those last 4. For the money though, if they last, I’m okay with my purchase. If all 5 worked I probably would have given them 5 stars, but I’m a bit aggravated about the fact the one that didn’t work was my favorite color...the pretty dark green watch. The face of each clock matches the band, but you can remove the watch easily from the band. Once the clock is in the band it is very secure.NoneLove the smooth texture, they only activate when you pull the plastic protector out so you don't waste the batteries but can use them sequentially. I have mine looped around my stethoscope. I can't pin it anywhere that I can also read it. LOLPretty colors, battery stoppers always a plus. However, the dark green faces are hard to see. Would've been nice if they had white numbers on that dark background. Would've made it easier to see. Otherwise, good deal, good productThese watches are perfect for nursing. I'm a CNA in a skilled nursing facility. I love the different colors and that they glow in the dark. My absolute favorite feature is the sweeping second hand. It is very easy to see and also has a glow in the dark dot on it.Small, light weight, flexible, and easy to read! Watches are consider jewerly at work and with the ability to talk on them they are not allowed in production areas. These are perfect for keeping up with time! Especially when documentation includes date and time of occurrence!One already went dead. Otherwise good.
