After wiping the lenses with the tissue that cane with the microscope I still cannot get rid of all of the debris seen in the attached photo. There are also cracks on the lenses that were on there when I got it. Terrible quality. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/26543013-21b-monocular-compound-microscope-640x-led-coaxial-coarse-and-fine](https://www.desertcart.id/products/26543013-21b-monocular-compound-microscope-640x-led-coaxial-coarse-and-fine) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-12*
