Review: Very satisfied! - For context, I am an amateur when it comes to microscopy. My use and interest is purely from a hobbiest point of view. As many do, I removed my oil objective and opted for this 20X. It mounted up easily provides a good crisp image. It only requires a slight fine adjustment when switching from my 10X or to my 40X, making it as if it was OEM. It would have been nice to have a matching color but given the price and functionality, the different color is purely cosmetic. I'd definitely buy this objective again.
Review: Excellent quality and fast service - The 20X achromatic objective lens (195mm optical bench length) was ordered on 5/6/2023 and received on 5/10/2023 (VERY prompt service). It has excellent optical quality for an intermediate magnification objective (to go with 4X and a 60X achromatic 195mm optical bench length objective lenses and provides near parfocal performance for a refurbished student microscope).

### ⭐⭐⭐⭐ Good value for money
*by D***W on December 1, 2022*

This lens proved to be a good match for my Amscope 120 and Swift 350 microscopes, giving images at least as good as the supplied 10x objectives. The field-of-view of 0.9 mm through the 10x 18 mm eyepiece was not flat at the edges, but the central area captured by a lens-less USB camera (0.18 mm) was good. Works fine with plankton samples as shown by the image of Ceratium.
