For first time buyers, -get one size up. Nothing stayed together. And it is also water proofed. My biggest complaint is the heel strap. Anker soundcore are my go to place for tech stuff. I recommend this product to anyone who is looking for a stand to hold weed trimmers. I know for a fact that these come in a BOX! This doesnt occur when ANC is turned off. Was loose at first. These Birks totally support my knees, my ankles, and all the bones in my feet.
