Summary: I wanted a spare of the USB ANT Stick that comes with my Forerunner 310XT. I thought it was pictured like the one here, but it is exactly the same tiny one that I have - which is easy to get misplaced or break. To be fair, I have not lost one nor broke one, but the product pictured here is not what I get.
Summary: I have owned a 205 and a 305 in the past and other than the short life span, liked the watch. The watch/GPS part of this functions well, but the ANT wireless data download fails constantly, has no consistent pattern as to what will bring it back to life.
Summary: I have been running with a 305 for several years now. It started to give me some trouble a few months ago so I started to look for a replacement. The 310 is the closest Garmin offers to the 305 so my wife bought it for me with part of our tax return this year. After less than a week I am trying to return it. The watch itself works well, the interface is similar to my old 305 and it syncs with satellites much faster. The problem is with the ANT connect.
Summary: Works great if you just want to use for running, however the low rating comes from problems with the softwear when attempting to load to PC. Uploading to PC or Strava requires multiple transfers of data and is very time consuming. If you plan on tracking your traning I would recommend another product.
Summary: I had the 305 for many years and loved it. It finally conked out so I got this one for the longer batter life and other upgrades. I'm a paddler - I do not usually have to swim (unless I go over...) but I need a waterproof watch for salt and fresh water paddling. So far, the 310XT has done well in that department. . Where this thing really fails is the data transfer. It is beyond me what the advantage of the ANT agent wireless data transfer is supposed to be.
Summary: I purchased this in spring of 2012 and am now on my 4th (3rd replacement) unit. Within the past few minutes, I contacted Garmin for service/return on this one and decided it was finally time to share my experience on Amazon. I have no complaints about the unit when it works but each one has gone through the same sequence: works fine for a short time; after a couple of weeks (unit #2/replacement #1 actually lasted for months), the unit requires hard/soft resets every time...
Summary: I bought this as a spare for my aging 305, in case the 305 after a long service would quit. All was well for the first year. But then, the software blunders amply discussed by other users prevented syncing with my Mac (and to date no way to uninstall this junk-ware). Over time, memory became full (of what? I kept deleting data to no avail) and satellite reception started to take so long that I went back to using the 305.
Summary: The watch works OK.. satellite signal is consistent and did not crash or freeze on all kind of terrains/locations.. Although the setup process could've been made less complicated. The biggest issue for me was the Garmin Connect software. I think it is very counter intuitive and full of bugs. I have 310XT and was able to install the software, pair and transfer data the first time.
Summary: My title says everything. I hate to buy replacement items, mainly when you spent a lot of money to buy the product, in this case the Garmin 310 XT. The original band didn't resist so much time, even in a regular use. I hope (and pray) that I won't need in the next future to buy one more band.
