Need this for $80 again please Woot! 
I have one of these and overall it’s pretty good. It does not support HVAC actuator recalibration on my 2012 GMC Sierra 2500 Denali, and I haven’t found any other cars it will do that for yet. It will do electronic parking brake (EPB) retraction on Subarus, mid-2010s VW/Audi products and a fair amount of others I’ve worked on. Just make sure to maintain battery voltage when doing EPB maintenance mode tasks.
