I purchased the Pioneer BDR‑XS07TUHD from Asmcom (uhdfriendlydrives.co.uk) on recommendation, and at his request, I'd like to share my experience here in the forum.
The drive was delivered quickly and securely to Germany, including an external power supply and in perfect condition.
Customs clearance went smoothly, and the package arrived much faster than expected.
Technically, the drive works flawlessly:

MakeMKV immediately detects LibreDrive

UHD ripping starts without issues

Read speed is excellent

First title I tested ripped successfully without problems
The seller was communicative, transparent, and friendly throughout the entire process.
You can tell he knows exactly what matters when it comes to UHD-compatible drives – no firmware risks, no surprises.
In short: If you're looking for a true UHD-capable drive and want a hassle-free, plug-and-play experience, Asmcom is the way to go.
