Review: Works great for my use. I recommend it.
Review: Couldn't be happier. Arrived on time and works as expected! Works for the newest bosch lineup as well –it was very unclear as to whether or not it would be compatible, but as of Octovber 2025 - the newest bosch lineup accepts this connection, letting you use milwaukee 18V batteries with bosch tools. I thought it might be worth mentioning; it might not look like the right connection in the photos, but I think that's because it's missing the pins required for battery charging—which was listed as not supported.
