I've got a 100mm travel 27.2mm remote one. It's not at all bad, but it's not as good as the RS Reverb. No lateral play in mine so far but I've only had it a couple of weeks. The action is quite stiff and a bit squeaky, and it requires a lot of weight on it to reach full compression. The remote is very stiff too, although you'll not have that issue. You'll probably need to top up the air when you get it or it won't return to full height (25 psi, hold the lever open when you do it). Put some carbon assembly compound on the saddle clamp, or it'll move when you're sitting on it.
So: it's not perfect, but it's much better than not having one.
