I've had an old Premier 5x7 red safelight for many years and no issues. I liked it so much I bought a new Premier 10x12 model and it's just as good. I think it safe to say I would buy another 5x7 if needed. I wouldn't buy the one on eBay, the seller is pushing the body color and ignoring what is important, the filter color. You don't know if it's OA or OC. I've been using dark red since the early 60's. I use a good bit of ortho material that requires it, there are some papers that require red as well.
