Theres an expression that youll read a lot on forums and its "I use these as my daily drivers". I love how light these slides are. It has nice battery life it lasted all day, the audio is perfect for taking call in the car and working out. The adhesive is sticky, but definitely not the same category as true 3M adhesive for similar products. But that’s Logitech for you. It is long enough to wear with heels but short enough not to drag the ground if I wear flats. The metal nozzle on the housing leaves me feeling a little better about long term durability. Glass bottles are high enough quality and the plastic caps are much better than average spice racks. At any rate, the mic is much better than the stock mic in the computer. These Muk Luks are:- great quality- always true to size, Medium (7-8)- ultra comfy- very durable- easy to slip on/off- no slip bottom- love the high contrast colors- recommend, again & again!
