I wasn't sure I *needed* another HRM, but I have gotten increasingly frustrated by data dropouts. I thought it was related to my battery, but despite changing it (in all three modules), I continued to have issues. I decided to buy the granddaddy of all HRMs, and WesternBikeWorks had the best price (as they often do). When I received the HRM, I was a little confused. I didn't realize that this module does not detach from the strap. It paired quickly with my head units (using Ant+) and I have used it several times since then. I have had no data drop outs, from what I can tell. Previously, my HR data was full of holes, but now I have a nice solid graph. Care for this one is a bit different - you rinse it after each use, then hand wash after every 7 uses or so. Replacing the battery will be easy - just peel off the yellow thing and it will become obvious. I like that this HRM measures running dynamics (still exploring this) and I'm finally getting consistent HRV readings. For me, it's worth the premium price.
The light appears to work as advertised. I use the daytime mode and it is very bright. Haven't measured the battery life, but it appears to be about as advertised.
Charging the light took some adaptation. It's not easy to unhook it from the handlebars each time to charge it, so I wound up putting a USB charger on an extension cord and charging it on the bike.
I lost the rubber boot that fits over the USB connector within the first month of use. Lezyne claims there isn't a design problem and you just have to make sure it's pushed on firmly. They're sending a replacement under warranty, I'll make sure it's pushed on firmly, and hopefully it'll last.
After my old Garmin fitness tracker died and my very old Garmin computer started fading, I decided to upgrade to something that could be used for both. I went with the S model to fit my small wrist, and while still larger than I'm used to, it is not overly bulky. Works great for all kinds of fitness tracking, phone notifications, and spotify playlists (when I don't want to take my phone for a run). As a bike computer, it connected easily to my existing heart rate band and cadence/speed sensors on my Trek. Using the navigation requires creating or uploading a route into Garmin Express and then exporting to the watch, but the navigation on the watch itself works well (tiny screen but the prompt beeps are helpful). I mount the watch to my handlebars using a rubber holder I got online, and it is sturdy and visible. Overall, very happy with the purchase.
A great feature set for riding. I've been using this on road, gravel and mtb with specific and customizable profiles for each discipline. The maps are great, and I was impressed at how accurate the trail maps have been. This is my first bike computer having relied on my garmin watches in the past. I've since added a cadence sensor and hrm, both of which provide good info when connected to the 530. One feature I thought was goofy, but have had fun with after riding with it for a while, is the 'jump' recording in the MTB profile. Measures distance and hang time, which of course has translated to passing this around to see who can go the biggest. I was skeptical, but jumped during the sale and glad I did.
