I ordered these loupes after comparing with the competition at the Dental showcase. The loupes feel premium quality, with the main features being: 1) lightweight frames considering the magnification (5.0). The frames are also designed in a way that means they don’t slowly deform and eventually crack (as my old ones did!) 2) The clarity of image is superb, and the depth of field also makes a big difference to operating use. 3) You can see the whole arch with 5.0 which is unrivalled with any other loupe on the market. 4) The light is excellent and the battery designed for this is revolutionary with no wires and easy attachment. 5) The whole kit fits neatly into a magnetic box, so you know your kit is safe and secure. Overall the product is fantastic and I’m enjoying using it. Not found any negatives yet. The service throughout has also been first class.
