great for the class room or plant pH control
Some plants need specific pH water to thrive. I use this to balance the number to where I want. ofcourse youll want to be in the lower ranges but they work great. Containers are well built and dont leak. I checked the pH with some strips and the levels were bang on. I thought for the price it was worth it.

Great PH calibration set
This is a great set for calibrating your PH meters. It came with 3 buffers, storage solution and a solution storage case (CalBox). I really like the CalBox. It makes it so much easier to calibrate my PH meter. Juggling small bottles is no fun. I also used one of the complements for distilled water. The only complaint I have is the CalBox lids arenโt water tight. If you do happen to turn it over, some will leak out. Its not a fatal flaw, just annoying. I was hoping to be able to drain one of the compartments as needed but its pretty much all or none. Otherwise I am very happy with the set!

Good value for pH references
These are the go-to reference solutions for testing the acid levels in wine. This brand has a 2-year expiration date. The coloration of these references makes it easy to not mix them up.

No issues in use. Storage solution is a bonus.
No issues. As expected. Storage solution is a nice addition. Tested against freshly cal'd unit and spot on.

Bottles were open and leaked
Amazon package was fine .. the apera box was fine that everything came in.. but the calibration 10.1 bottle was open an leaked about 3" down.. the 4.0 bottle was down 2" and the 7.0 bottle was down and inch from top. Only bottle that was sealed was the storage liquid ... not happy, not ordering from flamingo again

Lids loose; seal broken on storage solution
All lids not tightened. Storage solution lid really loose; seal broken causing liquid to escape and run down the bottle, crystallizing around mouth and down sides. Noticeably lower liquid volume in bottle.

Partially frozen
They arrived half frozen. Full of slush but the purchase and delivery went smoothly.
