Really good but..
This is a high quality product, it extends the VR's battery ... but, it is quity funky when it comes to keeping it pluugged while using the VR... for some reason, it stops charging the VR headset or charges at a very low speed... and sometimes it works like charm! .. a bit weird! I have the Meta Quest 3.
