    I’ve used several ohm readers from other company’s and the 521 plus tab is the best. I was sent the the 521 plus tab instead when I ordered this one which I’m super stoked about. Both are great units. If you’re into doing your own builds, these are essential! Especially if you have mech mods! Both are very accurate and they make building your deck so much easier than building on your mod. The other ohm meters available right now have not been worth the money. If you’re looking at this or the plus, but it.
