I've only recently started using them. I bought a bluetooth headset and gaming headphones from their recommendations, and I consider these two to be great purchases, with quality/cost ratio much better than the cheap stuff I used to buy before.

Agreed. They're extremely good about detailed reviews with pros, cons, and options for different types of purchasers.

for most things, yes. i went looking to sweethome about ceiling fans, and while information, it was a bit lacking compared to other categories
