Il prezzo è molto competitivo paragonato ad agitatori di uguale taglia prodotti da marchi più blasonati. Consiglio l'acquisto ### ⭐⭐⭐⭐⭐ Excelente *by M***N on 4 May 2024* Un artículo de gran calidad y potencia, gran fuerza de rotación con estabilidad. ### ⭐⭐⭐⭐⭐ Excellent rapport qualité-prix *by C***E on 4 December 2023* J'utilise cet appareil pour des préparations cosmétiques, émulsions, gels, lotions. J'ai pu mélanger des produits liquides jusqu'à 20 Kg. Le statif est bien stable, par contre la noix de serrage a tendance à pivoter à vitesse élevée et grand volume à mélanger. Très bien emballé à la réception. ## Frequently Bought Together - ONiLAB Electric Overhead Stirrer, LED Digital Overhead Stirrer Mixer with Stirring Rod，20 L ，10000 mPas ， 50~2200 RPM, Aluminum Alloy(Stand Included)… - QWORK® 5 Pcs Graduated Borosilicate Glass Beaker 5ml 10ml 25ml 50ml 100ml Set for Science Lab Kitchen - 10 Pcs Double Sided Glass Stirrer Sticks Heat Resistant Scientific Chemistry Lab Stirring Hot Cold Drinks --- ## 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.co.za/products/631571464-onilab-electric-overhead-stirrer-led-digital-mixer-20-l-10000](https://www.desertcart.co.za/products/631571464-onilab-electric-overhead-stirrer-led-digital-mixer-20-l-10000) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-18*
