Your purchase notes
Keep the details in one place.
Identify the equipment type and stated diameter first. Then read the manufacturer’s load and inflation guidance.
A small soft ball and a large stability ball serve different uses. Keep the intended use and exact diameter beside each item. A photograph does not supply a load rating or inflation pressure.
Plan the cost of your purchase
Explore your own cost-per-use scenario. Enter a realistic plan and include known extras. The result is arithmetic, not a claim about durability, performance or resale value.
