Very good quality for the money.

I bought three over the course of three years. One suddenly stopped working.

Works as advertised cheaper then most cloudlifters and works just the same! Used on SM7B and Samson q9u both worked phenomenal with this product!If your in need of a cloud-lifter alternative look no further, for this price you can’t beat it!

An inexpensive alternative to the "x"lifter. It has been working as intended in a studio environment for over 1 month now. Running through a frequency analyzer, it doesn't appear to add any noise or reshape the source's frequency input.Only thing that worries me is the XLR connection points seem a bit flimsy as the cable didn't seat in them well the first few times I used it. Hopefully, it holds up over time.As of today, I'd recommend it.

Bought this for my Shure SM7b. Paired it up with my Harmony h224 interface ad wow. Gain turned to about 12:00, came through loud, clear, and clean. If you're looking for a preamp that's half the price of the cloudlifter (love that donner coupon), give this a try.

I bought this with my own money, it wasn't given to me for free for a review. This booster was quiet and clean, the noise level was lower than Klark Teknik's. But it changed the sound of my microphones A LOT, to the point I didn't really recognize my microphone's original sound profile. It sounded like the sound from a pipe rattling and roaring. I returned after consideration. I really DO NOT recommend this product. I recommend a Cloudlifter or a Veeleiz Mica.

You get what you pay for and it's worth every penny. My old dynamic mic shines like a new penny because of this preamp.

My husband likes to record stuff for fun so I got this for him to try. So far no complaints. Clear audio. Easy to set up. And seem durable if you need it for travel.
