I'm quite happy with the Spooky2 as it can double down as a simple waveform /frequency generator.
That said I do wish the product developer made it open source so that the software could of been community driven as the existing interface feels rather limited in terms of programming and the likes.
That said, my favorite aspects of the device is where it can be used to run multiple profiles or a chain of frequencies with features such as soft start, wobble etc. Though I do wish it had better user customization rather than the table data style interface it currently has.
All in all I'd say the unit does what it's advertised to do and at an affordable price.
PS. do you find the output (v) to be too low? Have you tried the boost unit?
