Ultra-durable; will last a lifetime, synchronized JCC, auxiliary knobs are conveniently located near the bottom.
Most knobs and dials are a bit stiffer than newer Phoropters such as the Reichert Phoroptor, lens shift are a bit loud and crude sounding.
A great alternative to the traditional Ultramatic Phoroptor if you don’t mind stiffer knobs and a cruder operation.
If you’re in the market for a Phoropter, and yet budget is a big concern, the Marco RT-1 or RT-300 is a practical choice. Despite being a bit older than most Ultramatic phoropters on the market, the RT-300 still has a fully synchronized Jackson cross cylinder, and is assembled using only brass fittings. The result is an incredibly robust device that will last your lifetime (with regular maintenance of course) and look and feel a lot like the newer competition. There are some downsides: the buttons, knobs and dials feel a bit crude, and are definitely not as smooth or as easy as the newer Reichert device. The auxiliary knobs are also in a downward position which confuses or trips some people up- expecting that they’d be up top. Internal lenses however do have anti-reflective coatings with sealed plano covers– just like the new ones.
