I bought my cooling pad in February, 2016, so 11 months of use. The unit draws air down through the laptop and out either side. My laptop is a HP 15.7" and fits the pad quite well. A 17" laptop would overhang the sides some. My use is for heavy business use, but no gaming. I understand gaming computers have much more waste heat and as such I can not speak to that operating environment. For my use, the pad does a great job of cooling my laptop. After about 10 months of use, I noticed extra noise coming from the pad, especially upon restarting the laptop after it had been turned off for a few hours. Being an engineer, I had to investigate. (I was concerned there might be a bad fan bushing that would mean the end of the cooling pad was likely soon.) The investigation required disassembly of the pad, i.e. removing the four rubber feet, 6 screws, and the expanded metal grill covering the fans. My tools were a flashlight, a jewelers Phillips head screwdriver, a small flat head screwdriver, Q-tips, a cleaning cloth, and a can of canned air. What I found was a pronounced accumulation of hair on the leading edges of the fan blades as well as dust on the remainder of the blades. After a through cleaning and reassembly, the pad was running as quietly at the day I first put it to use. It would seem the hair accumulations had the small fans out of balance causing the pronounced vibrations that I had been hearing. Hair accumulations on the leading edges of fan blades in a common issue with portable fans used in the home. Also, I do have four cats. The disassembly and reassembly were easy enough. The only negative that I found we the way the expanded metal screen was secured into the cooling pad housing. Essentially, short extensions of the expanded screen were used as tabs that were then folded down into the housing. I could imagine these tabs could eventually break off during future cleaning tasks, due to cold working of the thin metal screen. This is a very minor issue only an engineer would be concerned about and does not impact the ability of the pad to do its function. For the circumstances described above, I consider this to be a very acceptable cooling pad for the money.
