Quality control/ Bauer jigsaw.
Bought the Bauer corded jigsaw. Blades would not seat. Returned it. Pulled another of the shelf. Same problem. Obvious design flaw. Got a refund. Then purchased a WEN jigsaw online from Home Depot. Same price range. Actually a few dollars cheaper, and everything worked fine. 3 stars instead of one because refund was hassle free.
