I find this Ubeesize to be the right weight - for ME. reached out to Samsung and they advised serial does not exist - most likely fake item and will not be covered under any warranty. I can?t wait to wear these out. by the second tournament we noticed he was limping in the shoes. Und nein, ich hatte normal saubere Finger! If you don?t have one yet. I have slight bunions though and these have a Narrow toebox and I dont think any amount of breaking in will make these comfortable at the end of a long day of hiking. I?m out of warranty since the replacement is 4 months after receiving them. This is not a tiny wireless mouse, it is more of a compact full size mouse. Especially if you have struggled with ear buds fitting or being comfortable.
