Rogaine foam vs Kirkland foam

[perrier]

Hi,

I've been Rogaine foam for the past 3 months and have been seeing positive results, however I'm on my last can of Rogaine foam and need to order a new batch. I can see the Kirkland foam is cheaper than Rogaine foam and I'm thinking of buying it instead. What will you advise me? Are there any differences in their behaviour (visibility, speed of drying out, etc) since the ingredients are the same? What is your experience in using it compared to the original?

Thanks!
