Review (4/5): Main blade won’t lock into place but got it replaced.
Unfortunately main blade doesn’t lock into place. The other two did but didn’t really need those.
Update. The company reached out about the issue and offered the refund or to replace. I took the replacement and it works as expected. Didn’t update to all five stars since I had to take extra time to get it sorted out but am thankful I got one that locks in place now.
