“Having recently joined Colt my team have been very welcoming. There is a lot of people who are willing to help and give their time so I can really adapt to my new surroundings and job tasks. I have responsibility already and I am trusted to deliver good work and really show my potential.”


The overall evaluation of the service received by Colt is positive in two ways: first, due to the technical quality of the product in terms of its strength, consistency and security, and second, in terms of the advice and assistance received during both the pre- and post-sales stages.
