About a month ago, I got a Garmin forerunner 15, and said I'd write a review, as its new. So here goes. I have no association with Garmin, other than as a customer. I bought my FR15 in Decathlon in France and paid the full retail price for it (150 Euros).
Background and reason for choice
I'd been dithering for some months about getting some kind of fitness tracker. I had originally decided on a Fitbit Force, but they never made it to market in Europe. Then I had a bad few runs with my phone's GPS, which had me thinking about an FR10. At that point, my beloved (who was supposed to be getting it as my birthday present) went shopping in Decathlon on what turned out to be the launch day for the FR15 in France. After a long heart to heart with the sales-guy he thought it was the ideal compromise, and suggested that I go for it.
I have a purple one in the smaller size. Although I have very small hands and wrists it is OK (although I wouldn't want it to be any bigger.

Nice and easy to use. There are only 4 buttons and all is pretty self-explanatory. Synchronization with the garmin connect site is nice and easy too. (Some people here dislike the new garmin site. Never having used the old one, I find the new one fine.)
The virtual pacer which is useful (set a pace then it warns you if you deviate - by more than 5% I think). I find I need to use the audio prompt - if it is on silent then the screen just flashes which isn't enough for me.
Run/walk lets you set intervals.
I use the activity tracker a lot more than I thought I would - basically i keep it on all the time. The goals are auto set (depending on your activity level) and it was genuinely illuminating and shocking to discover how sedentary I am on non-running days. You can programme it to give you a Move! prompt if you don't move around enough... even if you have done your day's steps, you will still get a Move! prompt if you stay sat down for a couple of hours.
Haven't tried using it swimming yet, but accidentally kept it on in the shower yesterday and it is still going strong, so waterproofing seems Ok.
Dislikes
The ability to set intervals longer than 10 minutes would be nice. Also the ability to set more than one value for each.
Overall
I'm very happy with it. It wasn't cheap, but I wear it all the time as a watch in any case (might not wear it with a ballgown or a really smart outfit but for every day its fine) and feel the price was OK for what it is.
