I've had several. It's a really nice Olympia-feeling machine with a strangely but kind of pleasantly short throw. The one I've had mostly have been on their last legs and a couple have died - admittedly ones I got really cheaply, one of which was broken when I got it and I thought I cond fix it  but it proved more difficult. I think any of the flat ultra-portables are more likely to be in slightly over-used condition, for the simple reason that they were used more heavily - being carried around everywhere... They were more likely to be in constant use, ie by journalists or students. Having said which, I currently have two that work nicely - one of which has been used to heavily that when I went to pick it up the return lever fell off in my hand! (It was only a fiver, anyway).

Got one.  Good typer and light in weight for travel etc.  Not in the SM class in regard to touch and typing pleasure, but a perfectly usable machine none the less.

Out of all of the ultra-portables that I've used, a Royal 200 (Nakajima), Olivetti Lettera 22, Smith-Corona Zephyr Deluxe, Remington Travel-Riter, and the Olympia SF (admittedly the Travel-Riter is a bit of a streeeeetch​) The Olympia is hands-down my favorite. The build quality is excellent as always, the design is contemporary to the period, and the touch is very good for what it is, though it is somewhat of an acquired taste. I would recommend it to anyone looking for a well-balanced ultra-portable.
