Madness, really great, 1A have, after long back and forth chose Bartscher Drink-Mixer 135 105, of course, the part is not very cheap, but the protein - shakes are amazing. Super creamy, just awesome. Have the gym quite a few protein -. Shakes made to me, but this unit is much better. The stainless steel mug is a nice size and you can optimally work with that unit is equipped with 2 speeds and me actually reaches level 1, with the lower suckers is the perfect drink-mixer. I find, therefore, 5 stars and high praise as appropriate, company Thank Bartscher.
