This product works great for hydrating and you only need a little. However, I'm giving 4 stars because the product is so thick that it was nearly impossible to pump out of the bottle. I then twisted off the pump top and the tube broke off inside the bottle! To Palmer's credit, they sent me a replacement pump and some coupons after I contacted them, AND they filled me in on a little clue to get the bottle to pump more easily: FIRST, unscrew and remove the pump from the bottle, then squeeze the bottle so all the air inside is removed and the product comes up to the top, then replace the pump and screw on. IT WORKED! Now it pumps easily with no problems. I only wish they had a label that said to do this, right on the bottle; it would have saved me months of fruitless pumping and frustration!
