521 TAB Mini Coil Burning Measure Building Platform V3 Ohm Resistance Tester

Nice meter it doesn’t come with an 18650 battery just an fyi and it needs one, battery cover is a pain in the butt to open and thin plastic but for the price still 5 stars. Most people will have an 18650 battery laying around I had to take it out of my mod to check ohms but it fires up and easy to use. Would buy again just it’s not as well made as I expected and battery cover will probably break soon but I also own duct tape so that’s an easy fix when it happens.

Ok so other than vape people, I have no idea why anyone would use this. Sorry I am not an electrician. So this review is for those who use it to check their atomizers and builds. The one thing I like about this, if you have all your wire, cotton, juices, tools for building, this all becomes quite a lot of items in 1 area. This being a "mini" gives you a little more working space. If you do your builds by a computer, watching some youtube or something, slap a usb in and good to go. It is accurate. Does exactly what it is supposed to do.

Works great for my boro attys to ohm and dry burn.

First day with the device and I've already used for multiple builds with a heavy nichrome coil style and its run strong/accurate. I tested on the build platform and on multiple mods, all showing exactly the same resistance.I was apprehensive at first (buying one of these at this price point) but I'm glad I picked it up. Shipping was ultra fast with Prime and the quality seems to be good. I will absolutely update if anything goes wrong but it seems to be working great.The only con would be that I wish it had indicators to tell you the battery level. I checked on my big charger and I used about 10% battery after prepping and installing 2 diff builds. I wrap my own coils and the process was on par with using a mod. Except this device was more comfortable.. albeit small (not too small.. just smaller than I expected). I give 5 stars bc the functionality seems good and i have had no problems thus far. I would def recommend this item to others.Build on the device is for a Pharaoh Mini, and the one on the mod is from a Loop RDA.

I have been building RDA’s since the advent of the RDA. I prefer to work with SS316, but you need this regardless of the coils material; to make a safe accurate build. I love that I can both get an accurate resistance, as well a burn cycle; to temper the metal, find hot spots, even out coil spacing etc. so I get an equal firing to both a dual coil or, ever a single coil. After it cools down I take my second ohm reading, and then add my cotton and juice it up.My only critique is that it’s not all that big. It’s about the size of my palm, so if you are looking for a large footprint, this is not it. It functions perfectly, but it is definitely not a build deck; as much as a tool for reading and burning.IMO this is a great tool for anyone the does their own builds, and wants to do so safely. Highly recommended

I tested this against my regulated box mods and the accuracy is spot on. Smaller than expected, but that’s my fault as I’m sure dimensions are in description. It’s a single 18650 in there, so when you go to fire it up, don’t expect it to start unloading clouds. It works and gets the coil glowing in about 4-5 seconds. Durability is yet to be known, but considering it’s all plastic, I would be careful with it. It’s worth it for $22. Just hope the chip lasts. So far I’m happy.

This is the identical product in the sale image, it’s not made by the legendary “Coil Master” but it’s whatever, it’s a well built clone. It functions just the same. Feels a bit flimsy, I wouldn’t try to go prying off the stuck cap of your RDA while is screwed into this, it’s not so much of a build deck. But everything else is solid.

Perfect to test your coil builds and dry burn. I did a test and compared the results of my coil build on both this and on my regulated mod, and they're either identical or within +/- .01 ohms, which is really accurate. Glad I got it
