Did u see they also have an expansion kit for testing flower %?? I know the pieces from that to but it individually and way cheaper! Instead of $150 for scale/ 10 syringes/ 10 syringe filters/ 10oz of 99% ISO instead I just bought a $35 milligram scale/ 100 1ml syringes for $12/ and 32oz of alcohol for $16! U use 1oz of the ISO for each flower test so kit that comes complete u only get 10 tests and then gotta refill it so easy and cheaper piecing it out!
