I agree the BOGs are great for local crud reduction and in a suburban area while the DX performance isn't great, the S/N impact just from ducking the noisy switched power supplies, chargers, garbage low voltage lighting switching matchbox transformers, PCs etc is significant. Even 100 ft wires on ground with a small tuner can be a big boom to receiving.
