I switched brands after a second can died after under a year of use, and so far am mostly happy with this Songmics. The lid is incredibly wide, making throwing trash away. It takes one more battery (4AA rather than 3 DS), but is incredibly silent to. It looks shiny and nice, although the brand name is visible (it's subtle and in a corner, but still visible). The bag holder ring is snug on a 13 gallon bag, and keyed (definite front and back), but all those points are minor variations.

The only real NEGATIVEs I've encountered is that the detection height is lower than I expected, so I'm having to lean down further to activate. In addition, it's a little slower to open -- but it's all relative.
