My Lenovo Ideapad 15.6 fits in the envelope. I'm not sure whether a few millimeters more space on all sides would not have been better. In the additional front pocket you can indeed store power brick and mouse, but the bag looks bad "dented" from. Alternatively fits my 10.1 Tablet with Belkin leather sleeve in the front pocket.
I use the bag Plemo primarily home to the notebook to store safely. But she is well suited. If you want more storage and transport in a laptop bag, which should probably look for a larger bag.
Shipping was no problem, so Amazon as usual. Even the packaging was okay.
