Product review (5 stars): Works as expected
Got into water sports lately and lots of wet stuff hanging around.  After much deliberate and help from the vendor and youtube community, I decided on the soft version.

The original one spinning at 3200rpm is also available right now for the same price.  Mathematically, it has 3 times the extracting power compare to the 1800rpm soft version.  Of course, it doesn't mean you are going to get 3 times more water out of the same load for apparent reason.  The soft version does a reasonable job, with less stress, noise, power consumption, and simply nicer looking to leave in plain view.

As for performance, never timed it, but I don't think I spin more than a minute or so, stop as soon as water start slow dripping.  Most quick dry fabrics come out almost ready to wear; cotton shirts have mixed wet and dry patches; bath towels need to hang overnight.  When perfectly balanced, it's really whisper quiet.  With a small tub and 1800rpm, this is approximately equivalent to a full size front loader spinning at 1,000rpm.  So if you already have the latest high performance front loader, you probably not going to get much out of it.  The 3200rpm version *might* help, but probably not by much, unless, like some mentioned, you are using laundromat machines that are programmed not to spin at full speed in order to squeeze more profit.

BTW, I'm not really sure if these are really "made" in Brazil, more like relabeled in Brazil.  What I do know is that they come out of China by the shipload for around twenty a piece.  Probably not matters to most people, just an interesting observation.
