Pump was ok- it’s important for the use of the large bucket of oil- the pump leaked a lot when fastening it onto the bucket, and would come apart from time to time. I was disappointed with the leaks, as it caused a considerable amount of loss of the oil, which is like liquid gold! Love the W3 oil, it’s been game changing for my antique TB who is a hard keeper. It’s an investment to purchase this oil regularly, so I try to get every last drop out of it- hate for any to get wasted. Pump did work most of the time I would say, just had to know how to finesse it to avoid leaks.
