We have a healthy respect for some of our colleagues in other firms. All we would like to say is that Boost has been in this business for fifty years and is working very hard indeed to be the most professional phase converter manufacturer in the world. We are very proud that we have made the first significant advance in the last decade or so by introducing our range of small Boosters with a symmetric neutral and many other advanced features as yet unmatched by any other manufacturer in the world.
