Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 551143. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed to fit the 2008-2013 Infiniti G37, 2007-2008 Infiniti G35, and additional vehicles. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to be certified by CARB for legal use in CA/CARB restricted states for the listed vehicles.

Responsive and very comfortable!
Color: Blue, Color: Blue
My goals for a mouse are productivity and development, not gaming. Overall, I’m a really big fan of this mouse and will be keeping it as a primary mouse. This is my first ergonomic mouse. This mouse fits perfectly in my hand and does not strain my wrist or fingers. It’s extremely comfortable to use. It worked out of the box with no additional software, a huge plus as I need it to be usable with my work laptop. The clicks are not very loud, which is great. The battery lasts a very long time. The little thing I love the most is that it came in a cute color, instead of just the standard white and black. It’s a cute, responsive, comfortable, affordable everyday house with no extra software and confirmations needed for it to work. I love it. That being said, it has things to note. The scroll wheel is very basic, no fancy scroll features unfortunately. It’s not loud, but just basic. The volume scroll wheel is a little high, sometimes I hit it by mistake. Neither of these are big deals. If I could change anything about this mouse, it would be swapping the volume scroll wheel to a horizontal scroll. I have 4 ways to change volume across all my desk devices, but 0 ways to scroll horizontally. Finding a vertical mouse that provides horizontal scroll functionality without additional software is nearly impossible. That feature would make this mouse a favorite for productivity IMO.

Very nice and comfortable!
Color: Pink, Color: Pink
I have carpel tunnel syndrome in both hands, and using a regular mouse hurts my hand. My friend told me to buy an ergonomic mouse, so I said sure. I've never used an ergonomic mouse before or one that is turned on the side like this one. However, I bought this one because of its high ratings. I love this mouse! It's comfortable, easy to use, and has high quality. The color is great too for all of you pink lovers. It comes with a USB cord to charge the mouse. All you need to do to charge it is to attach the cord to your mouse and to your laptop and let it charge. You can also use the mouse while charging it. I read someone else’s review. They said that if the mouse isn’t working or communicating for whatever reason, you can still use it with its USB cord, and the mouse still words. It looks like the company put a lot of thought into making this device, and it’s well worth the cost. I'm glad I bought this; my hands don't hurt anymore, and it’s super unique. When I started using this mouse, it took a little time to get used to using it on its side. I couldn’t fully wrap my hand around it, but I’m getting more used to it and it feels great on my hand. The thumb buttons are for going back to the previous page you were on, or going forward to the next page. The button on the very top of the mouse is for the volume. You can also press it down, but I honestly don’t remember what that part is for. The other side of it is the left and right clicks with the scroll wheel. There’s another button above the scroll wheel also called the DPI button that allows you to quickly adjust the mouse sensitivity. You will also find the charging port on the lower part of the mouse where it divides, and there are several other buttons and the USB receiver on under the mouse for connecting the mouse t to your computer. A user manual comes with this device that guides you through the setup. Shipping was on time and packaged nicely. I give this a 5/5 and recommend this product.

Love it! And... it can be remapped!!!
Color: Purple
Love it!! I'm a Mac user and it's been wonderful. Zero connectivity issues. The size is perfect too, my hand is like 7.5inches I think, and it was just right. What knocked it out of the park is that I was able to get the buttons remapped with Karabiner-Elements, so now I have custom shortcut buttons!!! I also read on Reddit that it can be remapped with AutoHotKey for Windows ;) It's ergonomic, responsive and quiet, and it works great with Bluetooth. Being able to remap it has made it the most perfect and affordable vertical mouse. Hope it lasts forever, we'll see how it holds up over time!

Durable, affordable, definitely buy it
Color: Purple
This fits so comfortably in my hand and I find that the layout of the clicker buttons is more efficient for me than a normal mouse. Tbh I don't use all of the functions but I know she's got more than I utilize. Moves smooth. For someone who has hand mobility issues or injuries (maybe even carpal tunnel?), this might be a better alternative than a normal computer mouse. It's good quality, durable, and I love the color options, I got purple/green with yellow. Super cute and worth the price. My husband got a $100 ergonomic mouse but I was not willing to pay that hefty price. 🤷🏻‍♀️
