I have some experience with mixer, so if funds are provided by the mixer, I'd have no trouble doing some testing. Altough, you'll have to keep in mind that I'm not an IT guy, so my review wouldn't be focused on the technical aspects of the mixer

I respect the fact you guys are doing the best to make your service popular but i dont see any reason why myself and others will leave long-existing bitcoin tumbler like Blender.io that offer service fee from 0.5% to 2.5% and make use of a mixer company created last year and offer see ice fee of 0.5% to 5%.
But for the review i also recommended loyce and Darkstar

You never know, and in my opinion it's better to have enough options with these types of services in as much as their long-term goal is to provide better security and remain in service, we've had multiple long-existing bitcoin mixers either getting seized by some Agencies or Exit scamming, which led to some thinking mixing might eventually go extinct.
