Well....
The Denkall Aqua Test is a great product. it slides right through a 25g pin with no problem. The only thing is it is only a 10mL vial. I am using the new Sydgroup Suspension right now and it kicks ass. It doesn't clog my 25g pins and slides through nicely. It comes in a 100mg/20mL vial for around the same price or a little less depening on where you get it as the denkall Aqua test. But both a great products.
