  Expensive, Heart rate could be more accurate

  Durability concerns due to plastic casing, HR sensor is not great for dynamic movements, Music playback doesn’t work very well

  App is difficult to navigate, Not the best-looking watch around

A great running and triathlon watch, with slim design, long battery life and now a much better price to go along with it. Although a little lightweight in nature it's more than good enough to function as a daily timepiece, and actually shows up some of the more 'dedicated' smartwatches.

  Plastic feel, Some fitness tracking could be better, Heart rate monitoring not great from wrist

The Garmin Forerunner 735XT is a little bulky, thanks to it being a multi-sport watch. We got the black and grey watch for review which looks pretty bland. However, this watch is for serious athletes, especially those who want to track performance across multiple sports during the same day.

  Bland looks, little bulky

I am so far very pleased with this watch for the following reasons: it is very light, comfortable and easy to adjust on my wrist It is very fast to detect the satellites and offers all the functions I need. I just hope the download clip will last longer than the one that came with the 210.

I have had this watch for almost 18 months. I did have exchange it for a new one when the main power/start activity button stopped working. It has simple functionality but the GPS is certainly not very accurate when running in the forest or mountains and often is off by as much as a mile for even a...

I have had it for a month, it connects to the app better than my previous Garmin watch (Forerunner 620). I have had it during swim sessions, biking and running. As far as i can see it has worked without a hitch.

This is a great product for tracking biking, running and swimming, not to mention monitoring all the things the Fit Bit does. Only better! This is the best fitness product to which I've been exposed.

i bought this watch to track my exercise, esp., triathlon training. out door running and cycling features are very straightforward and easy to use. GPS signal is very good and accurate. indoor lap tracking feature blows my mind off.

I bought this in May of 2017 after my other brand watch battery failed to hold a charge for longer than 4 hours a day. Saw this on sale at REI and decided to give it a go. First few months were great, no problems. Almost a year later, the whole thing crashed.

Very satisfied with the device. Very light and does not feel on the hand. Under water display is seen very good. Some of standard display color like blue is not recognizable in sunny days.
