If you change your mind, it doesn’t fit, or you become inflicted with buyer’s regret - that's OK!

Mike's Dive Cameras offer an extended returns policy of 30 days - so you can be rest assured if the suit, piece of diving equipment or gift doesn't suit then just send it back and we will either exchange it or offer a full refund less any postage costs. Too easy!
