Review on Enhance Your Raspberry Pi Zero Experience with MakerSpot's 4-Port Stackable USB Hub HAT (Camera Connector, Bluetooth & WiFi Supported) by Fred Griffin

Easy to install on your Pi Zero if you have a tiny Phillips screwdriver. I had to use an X-Acto blade to tighten the bolts (no big deal). Be careful with the spring-loaded pins when installing; It's easy to bend one of them so it doesn't touch the connection on the Pi. Well, *it* was easy for *me* to bend one of them, but also very easy to gently push it back on track. After my clumsy mistake was fixed, it started and just ran. Excellent technique and functionality, highly recommended. Deserves a 5 star rating.
