In use for 6 weeks now.  Super easy to use, quick charging. 
Was worried after ordering about 6 minutes use on Max, but I can pretty much do most of my house (5 beds) on Minimum. Use Mid for some areas and Max rarely for spillages.  
No complaints at all, equal in quality to previous Dyson V10 animal, but feels lighter despite good quality materials. Delivery was next day, as always from Samsung Direct, good communication.
