I do not have it, current price is a bit too high in my opinion - but it seems they are aware of the competition and bring some new options to the table. 10 LFOs can be hooked to a number of filters and 16 effects from the usual to formant, ring mod, fm... midi control, macros, etc. If the actual sound quality is good, may be worthwhile.
But this, like Stutter Edit and some others, is just a different category altogether. You add a specific LFO from ShaperBox when you need a specific effect, the amount of decisions you will make while using it is way less diverse. That is what I think makes ShaperBox so great, it is "just" a floating LFO tool with a very specific effect.
Infected Mushroom Gatekeeper from Polyverse Music does work like this too though and could be thought as directly superior to Volume Shaper depending on your needs, some features are just different. It can also pan, allows for midi control, cc send and apparently has cv output to modular - never tested this though.
