Digital Coil Resistance Tester Ohm Meter Reader Wire Coil DIY Tool for Coils Building Craft Hobby Use

This is the best ohm’s tester that I’ve had because it will pre-fire your coils gently when you only have mechanical mods it really helps. I would recommend using this device if you are a vaper to check your ohm’s before putting it on your device.

It's soooo nice having the fire button available without having to remove the deck. Good quality for the price. Works well. Uses only one 18650 battery...so not a lot of power. But, definitely gets the job done.

It work as stated. It is as accurate as the mod.It can be a tight spot if you are using a triple tree tool because the 510 connection is not squared up when tighten down so the atomizer screws always point to a corner which is longer than the tool. But if you use a longer screwdriver, it's all good.

This is a nice unit for the money. Many less expensive models only test for resistance, but this one also fires as well so you can prepare your coils. It is also very handy as a stand when you are rebuilding your atomizer.

Don’t buy unless your build are higher than 0.14ohm! It works fine but if you build around 0.1ohm this will not work. Lowest resistance rate is 0.1ohm and before you fire a new coil often resistance is lower (0.09) and it will not fire making it useless. Of course if your taste is higher resistance 0.14ohm + this product would be fine. Hope this helps.

I’ve tried plugging in a cave and used a fully charged 18650 battery. Nothing works. It shows power but nothing else. What a waste of money and materials. More plastic for the landfills.DO NOT WASTE YOUR MONEY.

Accurately reads ohms and fires any mod I put on it.I honestly don’t see the difference between this and a mod (besides a slightly awkward shape). Could totally be used a mod in a pinch if for whatever reason you don’t have access to one.

I like this ohm reader for my rebuildable dripping atomizers. The display is very easy to read and includes a switch to fire the coils after they are built.
