Terrible product. I have used plenty of drinkers over the years - impossible to get level . Maybe mine was defective ? legs also sharp on inside as just pure metal - so if trying to adjust easy to cut yourself.
Instructions poor - not clear if you haven't used this particular type - however I was able to identify how it should work and it still continuously leaked as despite being on flat concrete (where previous and new drinker have sat with no leaking..) seemed to not be level.
