I know the Altus isn't rated by Shimano as one of its higher-end derailleurs, but this was an easy and affordable upgrade to the stock cheap-o that came with my Schwinn and shifts easily, positively and is easy to adjust. It was slightly more challenging to install with the shims, but the advantage is it's a much more stable install-- very tight. I do wish I had searched a bit more and went with the lower-mount FD-M310, instead, as this one is just under one of my bottle holder mounts, but I never intended to use the downtube bottle holder, anyway, and it works and looks great, so I'm keeping it.
Like others have mentioned-- The cage is riveted, so you'll have to break your chain. Just my recommendation: If you're willing to break the chain, don't waste a whole lot of time trying to find a link to allow you to reuse it-- Just buy a new one (they are very affordable and typically come with a master link included) and a 2-way park tool to help you install and, if necessary, later remove the master link.
