Rated 5 out of 5 byDannyOKeKai808 from Lenovo Thinkpad Carbon X1 5th GenerationThis laptop is by far the best in quality and performance than any computer I’ve ever used and a I’ve used every major brands of laptop to date. I’m very pleased of the quality and service that I’ve received so far. I customed the X1 with the best possible upgrade available and although it was very expensive, it was money well spent. Its anti-glare screen hd display, quality of build and high speed have placed it at a whole different level making it the envy of every PC user even MAC book pro users. I was not surprised to find out that one of the major hospital we’re doing doing clinical training at stores these laptop as back up in case the hospital network and main computers ever fails.

Rated 5 out of 5 byDavid McReynolds from Sleek and functionalPerfectly functional and attractive case. Very close fit, but still allows wireless mouse receiver to be plugged in when the computer is in the case. A small pouch to hold the mouse would be a plus, as would be a sleeve to hold a few documents, but would take away from the sleek appearance. [This review was collected as part of a promotion.]

Rated 5 out of 5 byPhilR from Perfect, Professional AccompanimentThis sleek, quality, minimalist sleeve is perfect for my new Think Pad X1 Yoga (3rd Gen). To be able to carry around just my laptop in this case really puts a professional, elegant finishing touch on the whole package. It really just "completes the outfit." It's a no-frills accessory that only has one job and does it well.Branding is subtle and appropriate. Magnets are just strong enough to keep the sleeve both open on one side and closed on the other - so nothing is flapping in the breeze. Quality leather and neat uniform stitching with no lose strings or dropped stitches. Natural-looking grain and uniform color - as advertised. [This review was collected as part of a promotion.]

No place for the small mouse or even a thumb drive. This is very plain, cheap, and just plain out overpriced for what you get. Standard Protocol for Lenovo these days it seems.

Rated 5 out of 5 byFelimart from Elegant and subtleI liked it from the moment I put my X1 Carbon inside. Getting it out requires either grabbing the ThinkPad or putting the sleeve upside down from both ends and letting the ThinkPad slide out. The rubber feet create a lot of friction. On the one hand is a good thing as the unit will not come out accidentally, on the other hand I hope the drag will not take the feet out of the ThinkPad.

Rated 5 out of 5 byJivinjeff from The Perfect ComplimentI knew this was available when I purchased the X1 Carbon but I held off in placing the order until I could look around and see what the competition had to offer. Evidently, there was not anything that compared to the quality of this sleeve. It is the perfect compliment for my X1 Carbon and allows protection and storage of the notebook when not in use. It is extremely lightweight and of excellent construction complete with a pen loop. This is just a sleeve and not a bag, therefore, it does not afford storage of additional items. It will hold a pad of paper without any problems. It's a classy design and should last a long time.

Rated 5 out of 5 byJohnn from Good but could easily be great!I love the fact that there exists a case specifically made for this computer. It wasn't cheap, and I want to proudly display its logo on its case. I think the issue with this case is the material. It could be made of a big higher quality, and maybe include some ballistic nylon. My one major issue with this case is the inability to charge the laptop while its in the case without slightly moving the flap and pulling it out a half inch. There's no reason this laptop would get too hot while charging in the case so I don't see why they didn't have the cutout for that.The outside material also is pulling apart from the inside layer. I have only used this case for a few weeks. It looks great in the case. But when the case is empty the material by the thinkpad logo is starting to bubble out.

Rated 5 out of 5 byTimV from Module Storage?I have the X1 Tablet and this is a wonderful addition to that. I love this however I rated low as I really wanted something to solution my entire tablets modules as well. There's no room for the productivity module or the presenter module, much less the AC adapter.
