When considering if rental is the best option for you, often the deciding factors are invariably market confidence/uncertainty or speed. The alternative is usually to build but can you justify the capital spend? Other considerations include contract length, volume, and the speed of the solution delivery.
Furthermore, a rental option negates any capital spend with no associated feasibility costs and your solution can be up and running in weeks ensuring productivity is increased rapidly. The rental option is also incredibly flexible especially when you consider market uncertainty, and it offers bespoke contracts that can scaled up or down within the contract period to suit your needs.
