I wear one of these watches every day and have accidentally dropped them on tile and concrete floors without damage to the watch. The luminescence is bright, making it easier to read in darker environments. I happily recommend these watches.These are perfect for work. Much less cumbersome than pulling out my phone every time i don't have a clock around.I needed a watch that I could easily read while taking large animal TPRs and rumen motility checks. These watches clip onto my scrub top pocket and I can pull the watch out to comfortably keep both watch and possible flying hooves and horns in my field of vision while listening to the patient with my stethoscope. I have dropped them several times on concrete and so far no breaks. Easy to disinfect too.Recently I decided switch careers and work with animals. I am now a veterinarian assistant and going to be in school to be a veterinarian technician. I found out I needed a watch with a second hand. My cheap smartwatch that I have can only change to 4 faces. So since i already had a watch that had a timer, I decided to just look for a watch that could clip to my clothes. My scrubs have a spot where these watches fit perfectly. After using them for a few months I have noticed a few things that I would like to be different. I do like that they are retractable. It is also a bit hard trying to pull it out to look at it when I am trying to hold the pet to get the heart rate. So for me I do need something that is on my wrist. The one issue that I really have is that the clip part falls off. I used the black one first and the battery was still going strong. But at some point the clip disconnected at work. I found the clip in my pocket and couldn't find the watch. Days later someone found the watch in the drawer. By that time, I had thrown the clip away. Now I am using the red watch. The clip comes off all the time. I am thinking about super gluing it on. For the price, it is great to come with 3 watches. But not so good if you lose them because of the clip part coming off. For me these do what I need until I find a watch that I can wear on my wrist that is affordable with all the features I am looking for.The price was okay since it was for 3 watches. But I may invest in a better singular watch of the same price if it performs and last better.I’m studying to become a Medical Assistant and this watch has been so useful for vitals! Ilike that I can just clip it to my scrubs so it isn’t in the way like my fitbit was. The one downside is that it sometimes slips off my scrubs so I wish they were alligator clips instead. But other than that they’re really great. Also love that they’re glow in the dark.I am a veterinary technician. I absolutely love having this clipped to my scrubs. It helps me TPR when needed, even in emergency cases. I hate wearing watches. Whenever I pull the watch out, most dogs and cats will even stop and want to sniff it. I have given some of the other ones to my coworkers. I will continue to buy these as long as I need them. MUST HAVE. Rating: 10/10Good, quality product. Very good pricing. Wonderful product for caregivers of all settings. Will surely promote better hygiene and easy access.Love how the face glows in the dark
