I love the collar
I found this company through reddit and I'm so glad. I've bought cheap LED collars and lights before but they stopped working or weren't good quality. The Leuchtie mini is sturdy, looks well made, well designed, and I adore the two-color lights. The 27,5cm fits my 4kg Maltese just right and I like that it can be attached to the harness. The motion sensor is very high tech too.
