I didn't want to use 3rd party metal bands because I was afraid I would end up with a cracked watch back, and also due to the watch lugs design, they don't look good attached to the watch because they form a steep angle while exiting the watch, leading to a "hockey puck" look.
Finally the official metal bands became available via Amazon (the only ones shipping to a package forwarding addres - I live inside EU). I purchased the band for more money than I would like to spend but it was a must. I also purchased a cheap set of tools to help me replace it. I replaced the band in about 2 hours, being very careful not to scratch anything, and I succeeded to keep the watch intact. However, from this experience I advise you that this is not a simple operation and it's better to go to a jeweler. This is because the pins are hidden inside the watch and the original band takes up all the space and the pins are not visible and are hardly reachable. Also, the link pins are very hard to get out from the band in order to adjust, even with specialized tools. I really hope Motorola changes the band attachment and adjustment style on the Moto 360 v2, an easier procedure is sorely needed. Maybe they could take some hints from the Apple Watch
The band feels a lot better on hand compared to the leather band (strangely). The leather band was constantly reminding me that it's there, like I had some kind of allergy to it, I had to adjust it all the time, plus the bad smell. The metal band heats up to body temperature and you really don't feel it, despite being heavier. However, in my opinion, the metal band is about 1-2mm wider than ideal. Its actually 23mm instead of the standard 22mm. It's out of balance compared to the watch diameter and overall size. Another disadvantage of the metal band is that at the watch entry point the band looks unnatural, unfinished. The wide links end about 3mm before the rest of the band enters the watch, creating this "unfinished" effect. I think they could have done a better design. But this is a minor problem, overall the watch looks a lot better with the metal band. I do think it would look very good with the new cognac leather band, but I have to wear it while training so I can't use any more leather bands. Maybe a silicone band would come handy.
About the cracked back issue, the official metal band has 2 plastic pieces that are designed in such a way that the metal band never touches the watch back. Even the plastic pieces don't put strain on the back, it's very well designed in this regard.
