Review: Love Polar and Love the Grit X - I have always been a Polar user but did look around this time because there are plenty of good quality Sports watches out there for this price. I had the M430 previously and looked at many comparison sites regarding the Grit X. It's still pretty new and there's not a lot of reviews out there but based on what I read and saw I took the leap. Love this watch. It by far the best Polar watch I have had. The Heart Rate tracks in line with my M430 and the additional features all add to my current weekly activity really well (160k bike rides (Road and Mountain), walks and a weekly run - which I hope to build on). In particular the watch weight really makes a difference - I have never been able to keep a watch on through the night and therefore not ever tracked sleep. I hardly know I have the Grit on it is that light and comfortable. The charge is good - so far I have had three days of around 12 GPS tracking activities (around 10 hrs) and it is at 50%. I would highly recommend and really pleased I kept the faith and carried on using what is such a responsive, easy to use, robust and stylish brand. I would also like to say that I had an issue setting up the weather tracker and through using the website via messenger the tech support took 10 minutes to guide me through the process. Very impressive.
Review: Get one! - Brilliant watch. Been in use for 2 busy active months and will go happily for 3/4 days with about 2 hours of walking/running daily between charges. GPS super accurate, works great with komoot. HR sensor is accurate every time I've manually checked too. You can change the metrics easily and customise through the app. Which does take a little practice but neat feature. I've found it easy to read and easily bright enough. Basically not taking it off except to charge. My OH has an iwatch and is very jealous! I've knocked it against some fairly solid items whilst doing DIY too and not a scratch on the face. 2 minor criticisms: A couple of exercises have not been tallied correctly on daily tracker, although it does register them in the activity section on the polar app. I suspect the app is buggy. desertcart messed up the original shipping. Not an issue of the watch of course!

### ⭐⭐⭐⭐⭐ Cracking bit of kit!!
*by M***L on 5 June 2020*

5 years Polar user with a V800. Bought the grit X with a little apprehension due to bad reviews on Vantage watches. I don’t use it for navigation so can’t comment. I use a chest strap for HR as I would never trust any optical sensor. Had the watch 3 days and I love it and the extra options that have opened up in Flow. Love the suggested workouts on the watch which are easy to follow. Love the HR gauge when training. The cardio loading analysis seems really great as well and in general it’s a massive motivator. There was nothing wrong with my V800 and I was going to wait until it started to fail but couldn’t resist in the end and I’m very glad I bought this. Will update this as I go. I don’t have any problem with the screen brightness. I have no real experience of other brands so maybe it is duller than it’s competitors but it’s no more or less easy to read than my V800. Update 16/03/21 My opinion on this watch as I experience it more has got even better. I started to use the navigation features about 6 months ago by downloading routes from Komoot and using the watch like a sat-nav in the Peak District UK and I have had some of the best mountain bike rides ever, on my own, in the middle of nowhere without getting lost once. It really does open up a lot of opportunities when you use the product in this way. I do strength training 3 times per week and I do use a chest strap even though it not very cardio-heavy work, the difference between cardio load calculations with and without the chest strap sensor are massive (confirming that LED heart rate sensors are not reliably accurate and that if you want accuracy then a chest strap is essential). The sleep measurement and metrics are cool, I don't go into detail that much but it's cool to see how 'recharged' you are and this does concur with how you're feeling. Interesting to see how much even a small amount of alcohol impacts your autonomous nervous system. Has helped me to appreciate how much a couple of good (and teetotal) nights sleep impacts on my keenness to train and train hard. A few things have happened in the last 18 months, my dog died, I got an incredible enduro mountain bike, I got a Grit X to replace my V800 and of course COVID so all 4 things have impacted on my schedule in a big way but when I look at my training diary since 2016 I have done more training sessions in the last year than I have in the previous 5 years and I do put some of that down to the greatness of the Grit X.
