I have used API for years. When checked with Red Sea test API is just as good

If you are a dish or koi keeper, the API liquid drop test kits are the standard that other test kits are compared to. They provide consistently good, accurate, easy to read results in 5 minutes. Always buy liquid drop test kits over the less accurate paper strips.

API liquid kit is probably the best testing you can get, the accuracy is great & wayyy better than the strips! The individuals work just as well, but IMO for the price you’re actually better off just buying a whole new kit. They tend to lose the accuracy after a year or 2 anyway so make sure to replace them.

Can not get excited about reagents in a bottle with a 5ml beaker. So it is as described and does the job well.
