In direct comparison with another sensor trash can, I can say that the motion sensor of TecTake reacts very fast and reliable.
Securing the garbage bag works very simply and well with a fixed framework, one sees no trash bags.
I have the 50l bucket, it's perfect for the Yellow Sack garbage, all the smells stay inside.
Unfortunately, he was too wide for our kitchen, even the smaller models are 36cm wide. Because of attachment to the lid is always the same. Because I would have liked a smaller variant.
But technology and processing is only one thing to say: A 5-star trash!
ADDENDUM January 2015,
By the way is still the first set of batteries in it, and the garbage can (yellow sack) is served several times a day.
The sensor dustbin another company, bought at the same time, is now (broken hinge) is defective, this one is still like new !!!!!
