This product had consistently high reviews some places and few negatives in others, which you have to sift through to determine what's what. Negatives were mostly "product is leaky", which I chalk up to human error. Some complained that threads were of poor quality and special modifications to remedy situation, my opinion if there was defects it should have been returned and/or replaced by manufacturer.
My conclusion was to buy this firstly because it is all stainless construction, secondly it was from the company which produced the original dispenser and lastly because it came in the blue accent color.
This was a Christmas gift for my mother who actually uses this daily for creaming her coffee. I figured this was a no brainer with all the gadgets out there for whipping cream so why not actually buy a product such as this. Far easier, quicker and cleaner than using a wand mixer which you have to change batteries regularly. No clean up between uses vs. using the ninja frother which does well, but have to be careful with since its glass let alone pumping it up and down.
After using this product for nearly 3 weeks any potential negatives have been dismissed, it doesn't leak, it is easy to assemble and clean between uses and all machine work seems of highest quality and material. The initial cartridge install was the only difficult aspect, which actually wasn't a factor. Mother had never used one before and didn't want to over tighten not realizing there was a slight resistance at the point of seating the NO2 cylinder after which it threaded completely. She has had no difficulty what so ever, other than being heavy handed with the cream. One NO2 cylinder for one batch of cream which lasts about a week. Since buying this, I have noticed that *** has a new line of aerosol whipped coffee creamers.
