Laptop Stand Used for about a year. 【Adjustable Angle】 Adjustable from 12cm to 20cm, bringing the computer to eye level, maintaining proper posture, preventing neck pain and eye strain, and leading to a healthier life. (Note: Recently, there have been many counterfeit products listed by other sellers, so when purchasing, please make sure that the seller is Megainvo-JP.) 【Lightweight & Portable】 Weighing around 140g, it can be stored in suitcases, backpacks, and even handbags. Easy to store, it's useful for various situations such as travel and business trips. 【Excellent Stability】 Due to the carefully designed aluminum alloy triangular design, it has high stability. Furthermore, the non-slip rubber enhances stability. It is also possible to select stoppers according to the thickness of the laptop, allowing for secure fixation. In the unlikely event that the fixation is loose, cannot be fixed, or has severe tilting, we offer free exchange or return. However, as for our track record, we have shipped several thousand units to date, and the exchange and return rate for the aforementioned reasons from customers is about 0.1%, so we hope you can rest assured. Note: Please firmly push down the lock knob to secure it. If it's difficult to understand from the explanation alone, please refer to the usage photos in the "Product Description." 【Heat Dissipation】 The hollow design allows heat to dissipate easily, speeding up the computer's operation.
