Not so good. 🙁
This pump bottle had no good qualities - except for being cheap. It was flimsy. The  siphon/pump apparatus was way too short for regular use - it had to be filled within 1/2" all the time.  It spewed, leaked.  I simply threw it away - was not worth the trip to the UPS store 15 miles away to send back.  My advice:  do not buy.
