IKV have horrible customer service and not that great of a price break on getting alot. I got 10 atties one was marked 1.1 ohm off the rest where fine. I emailed them and they told me to try a analog multi meter. When my digital multi meter is maybe .2 ohm not 1.1 ohms off and the rest showed up fine for them. Also 20% of them dying in under 5 minutes I am never buying IKV again. Friends don't let friends buy IKV.
