Keys are sticking after a month of use. 2/24/2020 8:40:30 PM

Pros: Good when it works. But, problems after a month.

Cons: Is there anything less than 1 star? I have tried to contact the manufacturer on newegg and their site and I haven't received an answer. This was for a present for my nephew for Christmas. After less than a month of use the keys are sticking!

Overall Review: I wouldn't recommend!!!!!

Nice budget combo 2/17/2020 9:46:13 PM

Pros: -The colors are nice, but there aren't too many options.
-The keyboard is pretty great. The membrane does the job, but don't expect the same quality as a cherry mx keyboard.
-The mouse is okay and is good looking too.
-Good price for this combo.

Cons: -The mouse is small. I have big hands and i found that this mouse wasn't made for big hands.
-The mouse lacks of control for the colors.
-Lack of customization on both of items for the colors.

Overall Review: -Good for someone who doesn't want too much money on a keyboard and mouse.
-Does a good job for gaming, but don't expect the same quality as a cherry mx keyboard and high-end mouse.
-Lack of customization for colors.

Great Combo 6/5/2018 8:39:24 AM

Pros: For 50$ this was a great alternative to a high end keyboard and mouse. Hybrid mechanical switches feel so much better than the horrible logitech keyboard I use at work. Smooth, sturdy construction. The mouse was a good mouse. RGB on both of them. Not as many features on mouse as on the keyboard - referring to lighting.

Cons: Not fully mechanical. No cherry mx switches. mouse cable was ehh at best.

Overall Review: Good bang for the buck

Great Value but Disappointing Mouse 2/9/2018 11:33:37 AM

Pros: Keyboard is excellent, keys are responsive and true. The build is on the light side but definitely feels solid and sturdy. Color schemes are nice and the settings work as advertised. Price on sale was truly outstanding ($34.99).

Cons: Mouse is the weak link. Unreliable, all settings other than the color scheme settings seem almost random after changing to specific settings. Occasionally, the mouse decides to not track at all. Highly disappointing but in reality I bought this primarily for the keyboard only, properly functioning mouse would have been a nice bonus.

Overall Review: Would have given a 3 egg rating because of the shockingly unexpected, poorly performing mouse but the price was too good to squash a second egg on it, especially since the keyboard is great and it was the real focus of my purchase. Therefore, for the price I paid, I definitely recommend the purchase of this bundle even just for the keyboard alone and if you get a fully functioning mouse then you have gotten yourself a 5 egg deal.

Good Keyboard and Mouse, but not great! 10/21/2017 8:35:06 AM

Pros: The keys have a solid feel to them and works well for adjustments to the lighting. For the money I paid on the Shell Shocker deal it was worth the money if you're looking for a mechanical keyboard.

Cons: A couple of the lights in the keyboard aren't as bright as the rest? The mouse doesn't retain it's settings when you restart your computer. Another odd thing is, Windows doesn't recognize all of the mouse buttons?

Overall Review: Cougar could have done a little more to make this an exceptional buy. After using the keyboard for a day now, I'm really getting to like it more.
