The ZK amplifier board functions nicely—Bluetooth pairs quickly and sound is good. The instruction manual is a bit brief, but I managed to figure everything out with a little trial.

The EGS002 driver module is excellent for my DC-DC inverter. It’s stable, responds quickly, and integrates easily with my computer setup. No performance issues at all.

I’ve been using this Creatall AS21 amplifier for my home theater setup for a month, and it’s been fantastic! The build quality is top-notch—metal construction feels durable and premium. The TPA3255 chip delivers crisp highs, balanced mids, and deep, punchy bass that fills the room without distortion. Bluetooth 5.1 pairs quickly with my phone and smart TV, and the connection stays solid even through walls. I appreciate the multiple input options (AUX/USB/Bluetooth) that let me switch between devices easily. The protection features (overheat, short circuit) give me peace of mind for long-term use. The company’s customer service was responsive when I had questions about wiring, and the sample delivery was fast (arrived in 7 days as promised). For the price, it’s way better than some expensive brands I’ve tried—highly recommend for anyone looking for a reliable, high-performance amplifier!
