Mio Slice

If you're looking for an affordable multi-sport watch that has plenty of features and a sleek design, then you might just want to go with the Mio Slice. Unfortunately, the watch does not feature any sort of GPS tracking, but it does have a great heart rate sensor and message alerts that are based on your wrist. One of the things you should know about the Mio Slice is that it has a unique design that doesn't look like your average watch. Instead, it looks more like a cuff that you would use as an accessory. One drawback of this design, according to some, is that it makes it too stiff and rigid, not lending itself to a high level of comfort. Based on its functionality, however,  this is a great choice for a multi-sport watch.

    • Key Features
      The Mio Slice can be used for just about any activity, including walking, running, biking, and even swimming. As long as you don't go beneath 30 m, you'll have no problem swimming while wearing this watch. It's also fairly durable, so you should be able to take it out on mud runs and not have to worry about it smashing to pieces should you happen to take a tumble or two. The Mio Slice is an excellent watch for just about any activity in which you participate.
      Basic Features
      Some of the basic features of the Mio Slice include being able to track your steps and distance that you've covered on a run, allowing you to make sure that you get the proper number of steps each day in order to stay healthy. The Mio Slice is a very affordable watch. While this means that the watch naturally has less features than some of the more high-end watches that are out there. Still, the watch itself is capable of doing quite a lot, and is surprisingly high-powered for what it is.
      Advanced Features
      The Mio Slice is a bit lacking in advanced features, although it is capable of monitoring your heart rate like even the most advanced watches can. It's a bit slim on some of the other advanced features that you might be looking for in a multi-sport watch, but what it does it does well. The advanced features aren't this watch's strong suit, but that isn't necessarily a deal breaker.
      While advanced features aren't necessarily the strong suit of the Slice, it definitely does just fine in terms of accuracy. If you're looking for a competent watch that can track your distance and steps, then this is definitely the watch for you. It's been lauded for being quite accurate in that regard, so you won't have to worry about a possibly wonky step counter, something that unfortunately plagues even some of the most high-end multi-sport watches out there.
      It should be noted that while the Mio Slice does indeed feature a basic app for connecting your watch to your other favorite devices to track your data, the app is just that--basic. You shouldn't expect the app to be able to do all of the things that you might get out of more comprehensive programs, but it'll be more than capable of doing the basics that will allow you to keep track of all of your data. Just don't go in expecting this watch to be able to do it all, as it is fairly basic and at an affordable level that won't allow you to do everything.
      As we've touched on earlier, connectivity is definitely not where the Mio Slice excels as a multi-sport watch. It doesn't feature a wide array of apps like some of the other watches do. Instead, it sticks to its guns with a single proprietary app that covers most of the basic functions of a watch and allows your data to be transferred seamlessly. There's no support for third-party apps, either. With that said, if you're simply looking for a wearable that's affordable and can do the basics, the this watch might just be for you.
      Reviews have argued that the body of this multi-sport watch is a bit rigid, while the strap itself is likewise stiff. It isn't to the point where you'll be facing serious discomfort as you run or do whatever exercise it is that you're doing, but it is definitely something to note. This watch doesn't quite measure up to some of the other watches out there on the market, but the Mio Slice is a good option for someone who wants a simple, affordable introduction into the world of multi-sport watches.
      We've had to dampen your expectations a bit with the Slice, but this won't be the case when it comes to style. This watch has a very unique style compared to other similar devices. The face, instead of being round or squarish, as is the case with most watch faces, is rectangular, stretching up and down seamlessly into the watch's band itself, affording you a unique look at the data on your watch as you perform.
      The Mio Slice multi-sport watch doesn't just look good--it handles adversity well also. This is due largely to the fact that there's a relatively solid, simple construction to the watch, with the face lying flush against the rest of the watch and blending seamlessly into the watch's band. In this way, you can expect the watch to be able to avoid the pitfall of a lot of other watches -it won't crack under the pressure, literally. You can take this watch out with you on a mud run without having to worry about it cracking to pieces should you take a tumble.
      As we've touched on earlier in our review of this multi-sport watch, it has a really unique, interesting face that's sure to turn some heads as you're running, biking, or even swimming. The face is rectangular and extends up and down to link up with the band in a seamless fashion so that the watch itself seems to be made out of a single, uninterrupted piece. This serves the dual purpose of ensuring that the watch is just that much more durable while at the same time looking quite aesthetically pleasing.
      The band on this device is a bit of a double-edged sword, as it's a bit rigid and stiff in terms of fit, but it's also quite sleek and can stand up to a dunk of a 30m depth, meaning that you could easily take this watch out with you on a triathlon and not have to worry about it dying on you once it hits the water. The band on the Mio Slice might not be the most impressive thing out there, but it's definitely a plus for a multi-sport watch that has a collection of negative aspects. The Mio Slice is definitely a watch to check out.
      Sizes Available
      Instead of opting for a watch band that could be adjusted to fit a wide variety of wrist sizes and thus appeal to a wider audience of athletes, Mio decided to instead make a watch band that isn't very adjustable, but can fit the average person. This is a risk to be sure, but it mostly pays off for the Mio Slice. The watch will most likely fit your wrist, though its stiffness might mean that it won't be quite as comfortable as you might be hoping for. Even so, the Mio Slice should serve you just fine in terms of its fit on the watch band.
      Ease of Use
      Since the Mio Slice is such a simple multi-sport watch, the ease of use is notable. Where you might be fiddling with a more complicated device's input and swiping through screen after screen to get where you need to go, this simply isn't the case with this offering from Mio. This is because all of the data is located in a convenient location that gives you a view of all of your information in one centralized place. You should have no problem keeping track of your data with this one.
      Power Source
      Since this is such a simple multi-sport watch, you can expect the battery life to be pretty great. Where high-end watches have processors and bright screens that drain the battery fast, the Mio Slice benefits from a simple design that allows you to get upwards of five days of functionality off of a single charge. You should know, though, that the Mio Slice does require a proprietary charging dock in order to function, but the extended battery life more than makes up for this fact. If you're looking for a multi-sport watch that will go the distance, the Mio Slice might just be the watch for you.
      As we've touched on earlier, price is where the Slice really shines. While it might not be loaded with all of the features that you might be able to find in more advanced watches, it is more than capable of handling the basics, and it's offered at such a low price that you can potentially buy a second watch as a backup should the first break. As of the time of this writing, you won't have to pay any more than $130 for this watch on Amazon, and you could potentially pay as little as $80.
      There aren't any accessories for this device. If accessories are very important to you, then you might want to look elsewhere for a multi-sport watch. If they aren't incredibly important to you, then you should still consider this offering from Mio. After all, it does have plenty of other great features that make a purchase worthwhile.
      Key Features
      - Great tracking
      - Accurate step monitoring
      - Clear distance tracking
      - Encourages activity
      - Slick design
      Bottom Line
      The bottom line when it comes to the Mio Slice is that while it does lack some key features that you might be able to find elsewhere in a multi-sport watch, the features it does have are quite useful. IT also offers a unique design unlike other watches on the market. It handles the basics with ease, and it's tough enough to stand up to abuse that it might sustain on a tough mud run. Offered at a very affordable price, you could even stock up and get a backup watch if you so desire. The Mio Slice is a sound choice for a multi-sport watch.
