apparently the build quality is very good, but...
Rings is notoriously hard to tune - even with full size pots & knobs - the trimmers that are used on the micro clones are very poor in terms of precision - so if being able to tune the module is important to you - and it may not be - then I'd steer clear
things to think about
reduced size = poor ergonomics & eurorack is already on the 'small side' - personally I prefer bigger modules with full size knobs - all my mutable modules are full size - either originals or DIY versions
support the original designer where possible = whilst micro cloning is not completely without effort, the much more effort went into the original design - not only the hardware, but the firmware
support = can't comment on support from cloners, but Emilie is fantastic at support!
price = are you really saving that much - mostly it seems to be a good night out on the beer... so in the big scheme of things it doesn't seem like that big a deal to buy an original to me over a cheaper clone, especially if originals are still available!

Utility modules are the dull polish that makes the shiny modules actually shine!!!
