+ High-quality, solid metal construction+ Sturdy and dependable design+ Comes with pre-applied 3M adhesive and an extra set for repositioning+ Low profile when folded for easy portability+ Great value compared to similar products- Height adjustment options are very similar with minimal variation- Height specifications in degrees are hard to interpret into precise measurements_____I recently got myself a macro keypad (amazon.com/gp/product/B0BQJMPYDX/) to pair with my keyboard and boost productivity. For aesthetics—and also for reachability and convenience—I needed to raise the keypad to align seamlessly with the keyboard. I thought these risers would help, but unfortunately, they didn’t work as expected because they raised the pad higher than I wanted, even when using the smaller leg.To be fair, this isn’t a fault of the product itself—it’s on me for not checking the dimensions more carefully. While the dimensions are listed on the product page, the actual height they provide isn’t clearly stated in a way that's easy to visualize. The height is mentioned in degrees, which can be tricky to convert into precise measurements.That said, the quality of these risers is outstanding. They’re made of solid metal, neatly machined, and feel sturdy, dependable, and steady when in use. The 3M adhesive is already applied, and they even include an extra set, which is super convenient if you decide to reposition them later.The risers have a low profile when folded, so they don’t take up much space in your bag. Additionally, they feature silicone pads to protect the surface they’re placed on when folded. They also offer two levels of height adjustment, but my one gripe is that the two levels are very similar. I would have preferred a greater difference between the two settings—for example, keeping the higher level as is but offering a much lower option for added versatility.Overall, I’m deducting a hypothetical half-star because of the limited variation in height adjustment. However, when it comes to build quality (and the bonus of including an extra set of adhesives) and overall value—especially compared to similar products—this is an excellent purchase. Highly recommended.
