The mixer is made of good quality material BUT fails to do its only job, that is stopping water when handle is closed. Water keeps dripping at a really fast pace so it's useless. When contacted the seller with proof of what's happening, he said to make sure the handle is aligned to the tap! I've been on this planet for 34 years and know how to use a mixer!! Don't like writing bad feedback but when an item doesn't do its only job, you gotta warn others. Sorry for that. Maybe mine was defected but at least send a replacement and not offer a $2 refund.
