Radio. Our experience with TraVek is be far the best we've had. TraVek remodeled our kitchen a year ago and even though we had problems with one of the applinces (which was not part of TraVek) They made some calls for us and the result was amazing! Every time we have called Scott Schweda, our contractor for TraVek, he has gone beyond the mark with all our requests. Finally, there is a company (and contractor) who cares more for their customers than they do for their own interest!
