IT COUNTS 10 INCHES AND I GET 11 INCHES. I TRIED ADJUSTING NUMBERS BUT IT WOULD COUNT CORRECT FOR THAT LENGTH BUT WHEN I CHANGED THE LENGTH IT WAS OFF AGAIN. USELESS!!!! ### ⭐ Review *by L***N on 10 March 2025* Electronic unit failed after the first use. The instructions were for another electronic unit, and can't find the right instructions on the web. ### ⭐⭐⭐⭐ Review *by D***K on 26 May 2025* I’ve got 4 of these devices on a pilot paper machine to read out fabrics stretch position. In general they work very well. The one issue I have is with the encoders. They are light weight and not robust as an industrial unit should be for our use. Specifically I have found one intermittently skipping pulses apparently due to stress put on the input shaft. If things are free floating it seems to count ok. But if a ridged mount is used, these light weight encoders occasionally can stop counting. If you use care with mounting, these light weight rest of this system works well. ## Frequently Bought Together - JIAWANSHUN Digital Length Meter Counter Mechanical Length Counter Single Measure Wheel Unit in Feet Meter with Control Function 0-999999 Input 100-240V Output 12V - Zulkit Electronic Enclosures Blue Metal Enclosure Project Case DIY Box Junction Case Enclosure Preventive Case 6.7 x 4.3 x 3.1 inch(170 x130x80mm) --- ## 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.vn/products/689956217-jiawanshun-digital-length-meter-counter-mechanical-length-counter-single-measure](https://www.desertcart.vn/products/689956217-jiawanshun-digital-length-meter-counter-mechanical-length-counter-single-measure) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
