Canon Speedlite 420EX External Camera Flash

External camera flash, bought used and refurbished. I thought I was going to get into flash photography, but I never ended up using it. They showed me it worked in the store, but I never tried it on my camera. It takes 4 AA batteries. The battery cover at the side doesn't lock into place well so used black masking tape to hold it together. It makes a buzzing noise when turned on. I assume its normal because it did that when I bought it.

Looking for $100 value , 10,000 btz Pick up only downtown toronto near sherbourne subway station.

Side note. If you're a photographer or camera enthusiast interested in this speedlite and the Yashica film camera on my profile as well I can bundle them for less! Mind you they aren't compatible as is, but the deal still stands :)
