I purchased a Full Core Blade with special tip from Habbena:
5/5 on his service, communication and packaging of the blade. Answered my Pms promptly and sent a tracking# once shipped.
On the blade itself, I give it a 4/5- This is my subjective opinion on the blade itself and in no way reflects poorly on Habbena. The blade is similar to a VV diffused blade, with some light in a tube effect. The tip is bright, but you can clearly see the reflector showing through it, which somewhat spoils the effect. To be fair, I only tested it on 2 sabers, both 9 watt Tri Cree, one Blue, one VV's "OSPP" purple. Overall, while not unhappy with it, I still prefer VV diffused blade with their lit tip to this, and I still prefer a Trans white thin wall as my overall favorite blade type (with the exception of certain colors that would wash out-IE VV 's OSPP, or Madcow's "silver" color.)
On other products, I would deal with Habenna again!
