Product review (3 stars): Hard to install - cannot find an adapter to fit a Moen pull out faucet/sprayer.
It was not compatible at all with a Moen pull out faucet/sprayer.  Could not find right size adapter.  Ended up buying a whole new Moen faucet with a side sprayer and also hoses for underneath sink. If I would have know this much trouble, would have purchased a name brand so I could get parts easier.  Anyway set aside all that trouble, it works good and serves its purpose.
