Installed two packages two weeks ago. I peeked last week to see if they were straight, and they seemed to be. Looked a little closer today, and have 6 or 7 nice straight combs. They work fast!!
Funny thing, on one of the hives they did not build anything in front of the follower. I installed on the opening side, but they moved under the follower and built on the other side. All straight and nice. I removed several of the bars near the enterance and slid the occupied bars closer to the enterance.
