I like a key that is small enough to store easily in my toolbox or garage drawer. If it’s compact, I can keep it nearby whenever I need to adjust my sprinkler system. Portability is a small detail, but it makes a big difference in convenience.

Price vs. Value

When I compare prices, I don’t just look for the cheapest option. I want the best value for my money. In my experience, paying a little more for a reliable and well-made key is worth it if it lasts longer and works better.
