Almost a Five Star
I have used this brand exclusively on my BMW (110K) and Volvo (90K), with synthetic oil changes at 6000 miles religiously, and neither burns a single drop of oil. I have never seen any "failure" of the filter, which remains firm until the end. Unfortunately the price advantage has been eroding over the years- boo. So lost a star for that-

Coolant hose
Very difficult to get plastic part with o ring installed to slide into opening. It needs to extremely clean and add lubricant. I had to use a lot of force where I was worried about breaking plastic end. It’s been working perfect.
