Very positive reviews
Very positive review, despite comments about delivery time—no issues on my side. The screen was shipped the day after I ordered it, and the PC arrived 3 days later.
The PC works perfectly well and is well packed for transport.

I bought from flow up.
I recently bought a PC built by Flowup and the experience is flawless. The assembly is ultra clean (perfect cable management), the components are high quality, and the performance is exactly as promised—if not better. Special mention for the secure packaging—the PC arrived in perfect condition. I recommend it 100% for anyone who wants serious power without any hassle!

FAST DELIVERY AND EXCELLENT PERFORMANCE.
I received my PC in exactly 9 days! (Order placed on 10 February and received on 19 February). I’d like to thank the Flow Up team for their speed and honesty.
About my PC, it’s the Savannah v2 equipped with an RTX 5060 Ti and a Ryzen 7 5700x with 16GB ram. It’s perfect for gaming at 1440p in high/ultra quality on big AAA titles with 80/120 fps, and for esports at 240fps in low/high quality (depending on the games).
