JesmondJester - I’ve used them all: IMS E&B single, IMS the single, VST single.

They all kinda work, but they are not as straight forward to use as a double basket. The spent puck is often messy and soggy. For the VST 7g, you’ll need a 42mm tamper. The grinder will have to be adjusted/dialled in for that dose and that basket.
Also, the texture of a single shot is not quite the same as the texture of a “split double”. But for £13 or so… you can always give it a go.
