This is my second attempt with Barska...honestly they are complete garbage. Both times the binos were not collimated and created a double image. Stay away. Poor quality lenses, very poor construction.

• How is the quality of the product? extremely poor

These are great. Slightly shaky but can be hand held. I have a tripod nearby when the arms get tired watching the bald eagles. They work great.

double image, one of the prisms must of been out of alignment, just unlucky, very help full and good turn round for full refund.

• How accurate was the sizing? sizing was very good
• Please tell us about the quality of the product. very good
• Was the product free of any manufacturer defects? no
