I like that dimarck is always looking for ways to improve their products, they are constantly coming up with new features or ideas which helps us keep our technology current in today's world of constant change! They have excellent customer service when you call them out number one option would be email however sometimes it can take time before someone gets back but if its an emergency then we just picket phone calls throughly so this doesnt happen too often! There really isn't anything i dislike about dmark technologies services as everything seems very well thoughtout from start to finish!! Just make sure your not getting charged by multiple companies because there may actually only need 1 provider who covers all aspects of devices such as phones tablets laptops computers etc.
