I received this device as a Christmas gift, and I am thoroughly pleased. The Edge 540 stands out as the most remarkable Garmin model currently available.
I bought a new 530 some time ago. For some reason the charging port developed a fault, I contacted by phone, was instantly given details and faculty to return the faulty device, 4 days later I have new 540 in my possession. No questions asked. I am impressed with this service, well done Garmin.
So far so good. I love the features, I barely miss the touchscreen (especially since it cold out and I have gloves on most of the time). It loads quickly and tracks really well. The new climbpro is great and the training program I just started is pretty good. The battery life is impressive.
Having used bike computers from the big brands and ridden thousands of kms, this is my favorite one yet. The UI is so easy to use. The screen is great and easy to see and it's the perfect size for both racing and training.
