The Klaus is Bob Vila's overall pick for the category and Popular Mechanics' best traditional insert, and both awards come down to the front face: double glass doors, a mesh curtain, and a three-sided brick liner behind a resin log on a grate. It is a conversion product, meant to drop into a hearth or a framed cutout, and the flat bottom means it can sit straight on the floor of an opening with no hearth built under it. Popular Mechanics puts the output above 5,000 BTU for rooms up to 400 square feet. The reservations are consistent across both publications: the crackling audio does not convince, the control panel sits where you can see it, and there is no hardwire option.
- — Double glass doors and a mesh curtain in front of the fire, so the front face reads as a real firebox rather than a lit panel
- — Flat bottom lets it sit directly on the floor of a hearthless opening with no plinth to build
- — Three-sided brick liner behind a resin log on a grate, which is what Bob Vila built its overall pick around
- — Bob Vila's single con is that the crackling sound effect is not very realistic
- — Popular Mechanics calls the front-mounted control panel conspicuous on an insert designed to look traditional
- — Cannot be hardwired, so the cord has to be planned for or hidden
