### ⭐⭐⭐⭐ Review
*by T***N on 24 November 2024*

My only gripe is that it smells very strongly of wintergreen. Your instrument will smell of wintergreen even after you rinse it, meaning something is left coating your sensitive and highly expensive ph meter. This doesn't seem to impact performance however. And other reference materials are not as fairly priced, so its a good buy. My bottles arrived leak-free and were packaged well. I would reccomend this product as long as you can stand the minty-fresh smell that hangs around on your instrument for several days. Atleast it smells fresh i guess!
