Bought Trigger Sticks and they broke on the second or third outing. Had a huge ordeal with customer service and they wouldn't replace. Sent a letter to Bill Primos and they ended up sending me two sets. Sold both on eBay.
Round 2 was with the Boggear. First one arrived broken (clamp around extensions was made with cheap, brittle plastic.). Second set arrived broken at a different spot. Third set was the second set sent back.
Round 3 was with Cabelas brand tripod. Worked ok for first season, then it broke at the gear when I went to open it up. They somehow gave me my money back.
Round 4 is Harris bipod. Only regret is that I did the above 3 rounds to get here. Keep in mind I am very gentle with gear and shooting sticks are the only thing I have had problems with, knock on wood. Plastic moving parts just doesn't work in the wet and cold.
