The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer.

With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride.

Good value.
Style: Combo, Color: Black, Size: 1 Pack
I like the keyboard's light weight and compact size. The mouse is a little small. I have large hands and the mouse still works for me. The battery lasts a very long time on both the mouse and the keyboard. This is my second MK270 Combo. The first keyboard lasted over 10 years before the keys started sticking. The mice don't last near as long but for the price you can't go wrong. Note: I thought the keyboard was dead at first. When I checked the batteries, one was installed backward.

Comfortable and responsive
Style: Combo, Color: Black, Size: 1 Pack
The Logitech MK270 Wireless Keyboard and Mouse Combo has been an amazing addition to my setup! The keyboard feels comfortable and responsive while typing, and the mouse works smoothly with no lag. I love how easy it was to connect — just plug in the USB receiver and it’s ready to go. The battery life is impressive, and the wireless range is great for keeping my workspace clean and organized. Perfect for work, school, or everyday use!

Perfect Mouse & Keyboard Combo!
Style: Combo, Color: Rose, Size: 1 Pack
I love this combo so much I bought one for home and one for the office. I’m very picky when it comes to a mouse and a keyboard. The clicking sound drives me crazy. This mouse is very quiet and the keyboard is easy to type on. I love that the keyboard includes shortcut keys (calculator, volume control, etc.) and they actually work unlike others. I also appreciate the windows key - makes it easy to lock your computer when you’re away. The color is so pretty! Absolutely love the shade of pink. Highly recommend this product! Logitech is hands down the best!

Reliable and lasts forever Best budget option
Style: Combo, Color: Black, Size: 1 Pack, Style: Combo, Color: Black, Size: 1 Pack
I had this same model a long time ago and it lasted forever, I only had to get a new one because I lost the USB receiver, so I know for a fact they are very durable. For the price, you can't beat the compatibility you just plug it in and it works instantly. The appearance is very simple, it's not the most attractive or pretty keyboard since it has no lighting or fancy features, but it's built to last. The noise level is fine for a membrane keyboard, not too loud. In terms of ergonomics, it feels comfortable enough for daily work and the color is just the standard black that goes with everything. The best part is the battery life, it lasts months without needing a change.

Exceptional
Size: 22, Size: 22
Great quality and price. Monitors are exceptional. Would buy again without question. Screens are quite resilient, great picture. I bought three and use them in a multi Monitor setup for my work laptop, I needed something to view wireing diagrams and scan tool information qt the same time. If your a Service Technician looking for a multi Monitor set up would strongly recommend this Monitor.
