Sent them an email and go no response from them what so ever ## Customer Reviews ### ⭐⭐⭐⭐⭐ I'm glad I got one ! *by J***R on 2 August 2018* Checked the authenticity, all good ! Works well ! Great little tablet for building on, small enough to turn it about to get at awkward grub screws etc; clear l.e.d display, also gives volt reading as you dry fire your build. Light plastic construction, but seems sturdy enough. I'm glad I got one ! ### ⭐⭐⭐⭐⭐ Handy little helper. *by C***R on 10 June 2017* Never thought to bother with one of these but must admit, it really does help when building and re wicking. Everything is done on this little gadget from checking ohms to firing a coil up or burning of the gunk when re wicking. Takes a 18650 battery which is not included but if you are going to use one of these you may already have some to hand, this was checked and is a genuine product and is so handy that it is used on all the tanks, yes, we all tend to have a few!! The size, not TOO mini but enough to be stable in use and get in the usual bag of tricks. Surprised at how long I have done without one. ### ⭐⭐⭐⭐ Seems great *by M***C on 29 August 2019* Genuine coil master with scratch off. It's the second version (V2) and it seems easy to use and works fine. Haven't built on it yet just checked some premade to make sure it's accurate and firing well which it is. Will update when I've used it for a build. Ps DON'T FORGET TO ORDER A SEPARATE 18650 BATTERY.. as this does not come Inc. And I understand that many people have come unstuck on this point. I don't have a removal battery mod so I bought a single small charger and Samsung battery from Fogstar for around Β£10. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/48031987-coil-master-authentic-original-521-mini-tab-ohmmeter-multifunctional-mod](https://www.desertcart.co.za/products/48031987-coil-master-authentic-original-521-mini-tab-ohmmeter-multifunctional-mod) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-24*
