It is really nice that you can easily hear sounds like the footsteps of your enemy. Save yourself the money. But please! Cest pour cela que jai pris ce modèle de pantoufles Birk et pas un autre. ****************************************************Posted on 04/23/2021I have purchased ?Speed Stick Power Unscented? for years. Not all change is improvement. Pros:It only took 2hrs for the start up charge. I only wish they were a solid color but as long as shes happy, Im good. Very impressed with this product Bluetooth worked great no connection issues. Perfect for my OWB winter carry set up on my Walther PPQ M2.
