Kanger T3s are great but the replacement heads are expensive. Sun-Vapers has an upgrade kit that your going to love. Its a new base and replaceable head system that fits both the T3 and the MT3.
Instead of paying $2.99 per replacement, you now pay $7.99 for 5 replacements. Far more cost effective.
This upgrade for your T3's effectively turns them into the new T3S/MT3S coming out soon.
