Meh
The product doesn’t outright fail, but it doesn’t quite do the job properly. This is typically a product with mediocre performance, a poor price/performance ratio or a product that is a little behind the times. Alternatively, it could be a product marketed at overclockers that doesn’t overclock well at all. Better alternatives likely exist at a similar price, making the product difficult to recommend. It won’t set your PC on fire, but it’s just not as good as other products in the same market segment.
