Kezzler is very thorough and professional. They have a large team with a wide range of technical expertise. They really think through every detail of the project to make sure it is done the right way. They are very flexible and willing to customize or change the design as needed. It is a little difficult to get the product from Kezzler as there are so many steps and paperwork. You have to go through a multitude of emails and wait for responses before you can start the process. I have had to use Kezzler for several different projects and they have been great. They are the best to work with and they make the process easy. Kezzler has been able to help us track our devices and keep track of them as well.
