Coil Master Authentic Original 521 Mini Tab Ohmmeter / Multifunctional Mod / Vaping Coil Reconstruction Deck with OLED Screen

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 !

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.

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 £10.

Arrived quickly in perfect condition. I checked authenticity on the coilmaster website, using the scratch & sniff card, and this proved it to be genuine, not that I had any doubts, the packaging was off high quality, and sealed. I use this with a single LG HG2 18650 cell, this proved strong enough to pulse the coils on my RTDA, which is at 0.3Ω. I would recommend this for anyone who builds there own coils. Be aware that you will need an 18650 cell, and an external charger for this.

it's ok but the 510 adapters was loose so once I tightened up I could not remove the tank as it would just spin.. other than that worked as intended.

Really goid looking, and handy item. My old one just broke down, and I decided to buy a bigger than that. It looks accurate in ohm metering and the fire function makes my life more easier, as I don't need to swap the ohm meter and the mod while I (re)build a coil.

great bit of kit and amazing price. Here's a quick lecture for those getting into mechs. Please PLEASE buy one of these to check your ohms. You cant just build a coil and shove it onto your mod. This will tell you if you have any shorts etc. If it reads 0.0ohms when you build your coil and put it on this device you have a short. please vape safely.

This broke after a few uses.Initially it stopped reading resistance accurately. Then it would not fire, acting as if a coil was not attached.
