I have tried various products from ControlOMatic as a DIY expert and have continually been dissatisfied. Their cleaning supplies, chemicals, and water testing equipment all fell short of my expectations despite their claims to supply high-quality goods. The water testing kits provided false results, the cleaning instruments were flimsy and ineffective, and the chemicals did not perform as promised. I advise DIY enthusiasts to look for alternative brands for their outdoor space upkeep because it is obvious that ControlOMatic puts profit before the demands of their clients. Spend your time and money on trustworthy and efficient items that will ultimately save you time and energy rather than wasting it on ControlOMatic's inferior offerings. You won't regret it, I promise.
