Can you recommend any tennis balls?

For greater accuracy, consistency, and durability, we advise you to use pressure-less tennis balls. We usually recommend using Tretorn Micro-X or Wilson trainer tennis balls – with which we conduct all our internal tests.

All Lobster tennis ball machines are compatible with tennis ball for kids (which are typically green or orange colour).

However, due to the ever-changing number of tennis ball brands, it is impossible to guarantee and keep track of the specific brands that may or may not offer optimal results with the machines.
We strongly advise you to contact the manufacturers directly to enquire about compatibility with your machine.
