€599 is a strong deal against your local benchmark: it sits well below the €625 25th percentile and far under the €2,154 median for recent comparable listings. For this market, that’s not just “fair” — it’s priced at the bargain end, especially given how wide the upper quartile runs to €6,139.
What makes it worth a look is that grounding gear like this is bought for system-level noise reduction and lower hash, where the gains can be subtle but real in resolving rigs. At a clean good condition level, the upside is getting one of Synergistic Research’s more enthusiast-targeted accessories without paying anywhere near typical asking levels; just confirm the exact included cables/adapters and that it’s complete, because completeness matters more than cosmetics here.
