What Chinese Users Say

Liang Z. — JD Verified Buyer ★★★★★ “For ¥69 this cage is insane value. Fits my Sony A7C perfectly — no wobble, perfect cutouts for ports and battery. Add a SmallRig top handle (¥49) and a cold shoe mic and you have a proper video setup for under ¥200. My ¥400 SmallRig cage for my A7IV is nicer but not 6× nicer.”

Pan Q. — JD Verified Buyer ★★★★☆ “Good budget cage with one flaw: the cold shoe position is slightly forward compared to SmallRig’s, so some microphones may shift the balance. Works perfectly with Rode VideoMicro. The 1/4” screw is solid but I recommend adding a torque screwdriver — the included Allen key makes it easy to over-tighten.”

Wen F. — Taobao Verified Buyer ★★★☆☆ “Solid for ¥69 but the anodizing is thin — scratched easily on my first outing. Also the ARRI locating holes are not perfectly aligned — one of them is off by about 0.5mm. For a cage primarily used with handles it’s fine. For a rig with matte box and follow focus, get SmallRig.”

Lu J. — JD Verified Buyer ★★★★★ “Had this for 6 months on my A7C — daily use, no issues. This cage + a Peak Design wrist strap is my ultimate travel combo. The strap lug is positioned perfectly. Port access is all open — no need to remove the cage for USB-C charging. For ¥69, just buy it.”

Bao T. — SMZDM User ★★★★☆ “Ulanzi has done something amazing here: a functional camera cage for ¥69. The SmallRig equivalent is ¥249-349. The Ulanzi is heavier per gram but lighter in the wallet. Is it as refined? No. But it holds your camera securely and gives you mounting points. For that price, everyone with a compatible Sony should own one.”

Chinese competitors at similar price points offer comparable feature sets. The differentiators tend to be:

• App ecosystem: Some brands have more polished companion apps
• Build materials: Subtle differences in plastic vs metal ratios
• Customer service: Response times and resolution rates vary
• Brand reputation: Established brands offer more peace of mind
