Everything comes from China products reviews site purchased in China
My wife bought several of these rotating brushes, among them one of the Philco and one of the Mondial. The Conair is undoubtedly the best one.
The build quality is very good, starting with the box with a diagram of operation.
The body is metal brush, or at least of metallic paint, that seems to resist the time. Comes with an accessory for hair straightening (Liss) and a rotating brush.
The rotating brush comes in plastic casing.
There is the rotating brush has already docked:
You can remove the rotating brush for transport.
The top buttons are used to rotate the brush to one direction or the other. There are two levels of hot air and cold air.
There's the straightening attachment, It has a resistance similar to ceramic flat iron.
The part where it fits the brush resembles a common hair dryer. The rotating brush dry and brush the hair.
The back is also made of metal.
Unlike Phico and Mondial models, the brush seems to be more durable.
Comes with a manual and a certificate of guarantee.
The only problem is the price, that goes from 250 to 350 real. The quality of the product justifies being the most expensive rotary brush, Although I still think the difference for the cheaper models is too big. My wife was pleased with the product, so I guess it was worth the investment. I leave below links to purchase here in Brazil even:
