I bought the Edge 540 less than a month ago, and I'm very happy with my purchase. My first real bike computer was an Edge 500, then I upgraded to and Edge 820 eight and half years ago. The battery on the 820 was by now lasting less than 3 hours and I needed to recharge the computer at rest stops during long rides LOL!. A friend told me about his 540's battery lasting for several rides and I was sold! The battery on the 540 lasts 26 hours (advertised) in intense mode and this is outstanding for me. The 540 also has a bigger screen than the 820 and it makes it easier to read. I also opted for not having a touchscreen as my experience with the 820's touchscreen was less than ideal in the wintertime while wearing gloves. I was also super pleased with the setup process. I was thinking it was going to take me over an hour to set up my screens and data for my 3 bikes, but this was not the case. The setup process imported all the profiles and screens I had on the 820 and I was ready to ride with my new computer in just a few minutes.
Bought this some time ago but had to wait to use as I suffered a cycling accident hit by a car. Now back on my bike and thoroughly enjoying the new cyclometer and all the wonderful capabilities. Easy to set up and satellite connection is flawless. Keep up the great work.
I had to replace my 530 (which I loved and worked perfectly well - I just lost it somehow) and found the 540 at discounted price. I preferred the old menu in the 530 - it was simple to navigate - but now that I've had the 540 for a while I'm happy with it. It's faster to turn on and off, and it's easy to connect to the other sensors and phone. It's slightly wider than the 530 but overall comfortable (it sits in between my hands as I ride exclusively in a tribike). I really like the non-touchscreen design, with side buttons, as the touchscreens tend to change page inadvertently. it happens with the side buttons as well, but not as often.
I've used the Garmin Edge 540 on several rides now and works great! I like being able to see all my stats on one screen and having another screen for the map, so easy to use.
This is my second Edge 540, the first perished in a bike crash. I have had a number of computers over the years and this is easily the best, and fits my needs perfectly.
