The medium waxed frames purchased in 2023 have performed well in my Apimaye hives (7-frame NUCs & 10 frame ERGOs). Purchased another box of medium fames in 2026 to cope wth growth in my apiary. Bees have used them without hesitation. Easy to use for honey harvesting. Light & robust. Pack snugly in the medium boxes. Easy to add additional wax to frames (from cappings). Also used for placing sugar bricks for winter feeding (bricks made on frames (one side) & dried in place - rubber bands used to ensure bricks remain on frames / good success).
