I find it interesting to see these reviews and, frankly, wonder if they are not competitors vs. actual customers. This is the only provider that we would ever recommend as they have been incredibly helpful with resolving any problems with MVD (the real problem in this rodeo). They also worked to get things changed to benefit their customers and have a very high early removal rate. We have also had to deal with the corporate offices of DRAEGER and can compare it to dealings with the other providers and home offices. Those other providers refuse to provide proof that it was their instrument and seem to have a great knack for violating people at the end of their contract so MVD extends the time on the device. That is NOT our experience with SAFE HARBOR and the DRAEGER corporate office. HIGHLY TRUSTED OWNER AND STAFF.
