Two things appealed to me about the Coros Dura bike computer: it's price and the relative ease other reviewers gave for ease-of-use. Price is definitely favorable compared to other GPS computers but as for ease-of-use, I'm less sure. You will need to use the app to do most things, then sync the app on your phone with the Dura...that part is easy. Less so, is wading through the myriad of features you will likely not use to do what for me is the essential: mapping rides, importing routes and measuring distance, elevation gains and losses etc. I've had it a couple of months at this point and I've imported routes and used the routes for riding but I am by no means masterful at using it - I suspect it will take a more concerted effort yet. Overall, great GPS, just wish there were a stripped down feature for easier day-to-day use for those not training for a triathlon and don't need splits, laps etc.
I use this light as the main light for road biking, fixed gear, and gravel cycling. My secondary light is a Cygolite mounted with a gopro mount on my helmet. The Knog is pretty bright, though it definitely seems brighter offroad. Compared to the Cygolite, the Knog's light is a little bit on the yellow side, so that makes it wash out a little on the road. If the light is used by iteself, this isn't as noticable. I previously had a Light and Motion light (they went out of business) which has a much wider beam, but I can't complain too much. The usb C charging connection is also really nice as it charges quickly and is not a keyed connector.
I purchased this to help train for a 100 mile MTB race. I have used it on gravel and road rides so far. I was able to easily connect with a heart rate monitor. The owners manual was of limited help in setting up. Mostly relied on U tube videos to set up. I am pleased with this GPS but since I do not understand and alot of the functions and fields , I am sure I am not gaining all that it has to offer. I am 63 with 8 years of college but I own a flip phone and am technology challenged.
I have had many heart rate monitors over the years. Polar, and Garmin. This heart rate monitor is worth the extra money in terms of of performance. I have a swim Garmin HRM which is very similar but this one is more confortable. I have optical HRM but I prefer the chest strap because it uses electrical impulses to measure heart rate which is capable to detect Atrial Fibrillation; not so with optical technology. The storage is handy if you are doing a sport where you receiving device is out of range. At the end of the activity it downloads your heart rate data for the session. You have to make sure the device is connected to you HRM before you start the activity for this to work. The Bluetooth/ANT functionality works well also.
