Three different baby walkers are being recalled for safety reasons.

The recalled baby walkers can fit through a standard doorway and aren’t designed to stop at the edge of a step. The models raising concerns are made by three different manufacturers: Bike Pro, Inc., Ace Han Corp., and Sun Tome Trading Corp.

“Babies using these walkers can be seriously injured or killed,” states a news release from the U.S. Consumer Product Safety Commission (CPSC).

However, no injuries or accidents have been reported with any of the walkers, the CPSC states.

“Consumers should stop using the recalled walkers immediately and return the walkers to the retailer where purchased for a full refund,” states the CPSC.

Here are details from the CPSC on each of the recalled baby walkers.
