Try before you buy

Rent any piece of equipment from Castle's rental website www.castlerent.com, and if you decide to buy it within six months, Castle will deduct one week of the full rental price from the cost price of the instrument.

So, Castle Group says, "for a fraction of the sale price, you can have full access to the instrument in your own environment, at your own pace – allowing you to assess the effectiveness and suitability of the instrument for your own requirements."

And if it's the right piece of equipment for you (Castle's experts are available to consult with pre-hire), you'll be reimbursed the full cost.
