One thing I'd change is allowing us to use Feet instead of km. Yeah I can convert it.. but oh well. This product has saved me A LOT of time. now for me it has.. it may not for everyone.. depends on how detailed you need the OTDR to be. ### ⭐ Works fine till you lightly tap it on something. *by R***E on August 17, 2020* This is not a quality piece of equipment. The first one I had stopped working and I needed to replace it after I dropped it a literal foot off the ground. The second one barely got wet from a little rain and again stopped working. Its what I expect from crap made in China. ### ⭐⭐⭐⭐⭐ TL290T *by T***S on May 26, 2020* I work for an ISO and have been using this OTDR to troubleshoot and ensure spliced connections are correct. Using the OTDR, the Light Meter and Light Source all in one package has saved me a lot of time. The sellers service team have been very good to work with and have answered all of my questions. ## Frequently Bought Together - QIIRUN TL290T 4 in 1 Fiber Optic Tools with OTDR Fiber Tester, Optical Power Meter, Optical Light Source and Visual Fault Locator Functions Featuring 4-inch IPS Display - Signal fire Ai-20 Fusion Splicer High-Precision One-Step Fiber Cutter Integrated, Optical Fiber Fusion Splicer Core Alignment W/Built-in VFL & OPM Function and 3 in 1 Optical Fiber Holder - Jonard Tools BRT-100 Buffer Tube Binder Ripper Tool for Fiber Optic Cable Technicians (Pack of 10) --- ## 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.hr/products/146561470-tl290t-4-in-1-fiber-optic-tools-with-otdr-fiber](https://www.desertcart.hr/products/146561470-tl290t-4-in-1-fiber-optic-tools-with-otdr-fiber) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-07*
