I was worried my old adapter's straight plug would get bumped loose behind the desk, but this L-shaped one sits flush and hasn't wiggled once. The 7.5V 2.3A output matches my device exactly, and the 5.5mm jack clicked in snug on the first try.

The 90-degree elbow plug is a lifesaver for my setup—it tucks neatly behind the shelf instead of jutting out. Voltage and amps matched my old unit exactly, and it's been running cool for a couple weeks now. Solid buy.

Bought this to replace a dead adapter and the 7.5V 2.3A output matches my device exactly, no weird buzzing or heat after a few hours of use. The elbow jack also fits tight in the port instead of wiggling loose like my last one.
