The Logitech G software is around 270mb last I checked, is clean, functional and lightweight. I bought this on sale, at seventy USD. Aufsetzen, ausrichten und den Hebel runterdrücken. For those, including myself, who has a pudge I would recommend wearing a spanx with this waist trainer it?s not that long. Final verdict? As a common user, not needing to spend a small fortune of having an audiophiles dedication I really like these. After about a month, the sound started breaking up. We had 10 pair so for about $3 a pair it was still a much better buy than getting a $10 pair that would only last 3 days . Dance music sounds rich without muddy bass, vocals are clear and crisp. Upon opening the box I found instructions, extended warranty card, a charger, charging case, and headphones. I bought the 25 boned small waist trainer and Im extremely pleased.
