Nice design. The handle turns smoothly. However, a major disadvantage is that it gets dirty VERY EASILY. I have also purchased the TESI series sink battery from the same brand, which also has a big difference in this area. And any small amount of water that remains on the STRADA (which is impossible not to happen because it has wide horizontal surfaces where water does not flow) will leave a very noticeable outline (from salts) that is very difficult to remove, even with the use of AZACH! Every other battery I have (e.g. Grohe, Hansgrohe, even OLD MODELS of IDEAL STANDARD, etc.) cleans very easily even with a damp cloth or paper. In fact, this particular battery, after the times I have cleaned it with a cloth without strong chemicals, shows a bunch of small scratches... I regret buying it.
