Summary: I had purchased this garmin edge 500 bundle and within 2 weeks it stopped working. A "working..." screen came up and this was only about 7 rides. I called gamin and they couldnt get it working and decided or warranty it. After a week of waiting for emails on a exchange i had to call again to actually get them to send the emails.
Summary: This Garmin fails in all area for which it was purchased. It lost data on 3 of 4 rides, will not measure cadence or heart rate accurately, and rarely displays useful info. I am trying to return it, but because I purchased it during the winter and only recent put it to use, it seems Amazon will not return it. Stick with the edge 305 imo, it worked flawlessly compared to this heap.
Summary: Great product and functions but the HR readings become unreliable after ~6 weeks. Once the funny readings start, it will not work right on all subsequent rides. Indicates my HR at 8 bpm when it should be ~130. Then it gives good reading, then shows 40 bpm erratic. First unit.... I went back to the bike shop and exchanged for second unit. 2 months later, I returned for full refund. A year later, I am thinking they have it worked out so I try again.
Summary: I've had this Garmin 500 for 9 months. The first few rides were trouble free except the display is so small I can't read what's happening. The only function that works consistantly is pedal cadence. Quite often the speed dissappears and will later in the ride reappear. when this happens my total distance is off by the distance that was covered while the unit wan't working properly. The heartrate function is a joke. It often reads as high as 273 beats per minute.
Summary: I was very excited to purchase this as an upgrade to a $50 wireless Cat Eye. I was looking forward to using it to track my rides and for uploading to Strava. I setup with HRM and cadence. Initially I was excited about the HRM, cadence, and altitude tracking but also didn't like that the unit seemed to struggle with average moving speed.
Summary: I bought the GARMIN 500 thinking I'd have an all-encompassing, simple to use data collector for my bicycle workouts. Something I could easily track and review workout data -- mileage, speed, distance, cadence, & heart rate. The Garmin description of the 500 had me thinking this was exactly what I needed. However, the user interface for actually reviewing workout data is convoluted at best.
Summary: After two months of using my Edge 500 and communicating with Garmin about it's function and lack of function, I am returning it to REI. The most troubling issue it that it does not perform the mapping, directional guidance function that the manual says it does (more on that in a moment). The most annoying trouble is that the heart rate monitor performs erratically. First the positive. The data display on the Edge 500 is excellent.
Summary: If you believe that I can go 120mph on my bike I have some land for you. Computer will read 0 while going down hill pretty fast. Next time it reads 50+ mph. Sent it back got a refurbished unit same problem. Owned for 8 months worked for 3. Now waiting to hear from them. I expect more for [$] pass this one by.
Excerpt: Old fashion mounted one that counts wheel turns and a HR rate watch.
Pros: works great on the road. Clock and timer work well.
Cons: Doesn't work in the forest. Always about 20% off the distance. can't figure out how (if even possible) to display HR as opposed to calories. When downloading to the web doesn't auto delete so over time, gets super slow
