What is a JB4?

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing, including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated, the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.

If your looking for S68 tuning for your BMW XM or X5,X7 M60i, or 7 Series M60e the JB4 is a perfect S68 engine tune.

Great no-frills bag. Slim and compact, but still holds plenty.
Size: 17.3 Inch, Style: 1-pack
I needed a case for my new HP Pavilion 17" laptop. I didn't need anything fancy or with all kinds of special features. I didn't need one with a lot of extra storage space beyond what was required for the laptop, its power adapter and cord, and a small mouse. And above all I didn't want one with a large, bulky profile, one that would feel like I was carrying--or rolling--a small suitcase. Turns out this AmazonBasics bag was just what I was looking for. It is indeed slim and compact, and it's lightweight to boot (only weighing about 1 lb.). And even when it's filled to the brim and weighs a good bit more, it STILL looks slim and compact. For its economical price point, it is constructed very well, and thus should be quite durable for light to moderate use. The stitching is very tight and clean, with even strong, "zipper-stay" stitching being included on this inexpensive bag. The zippers themselves (which I tend to be picky about) are of very good quality, and open and close without much effort. The zipper pulls are ample in size and weight, and are very strong and sturdy. In other words, they're NOT cheap. I appreciate the case's simple yet thoughtful design. I especially like the single, large, zippered pocket on the front "face" of the bag, where you can easily and conveniently keep oft-used items such as your phone, keys, power bank, and so forth. Too many laptop bags' outside pockets are unzippered, which I find both impractical and unsafe. The AmazonBasics bag holds my laptop snugly and securely, yet I can still manage to squeeze in extra padding (about 3/8" thick and 1.5" wide) all around its perimeter. I do this because the case provides only the most minimal of padding throughout. (Mind you, I wouldn't have expected sufficiently thick padding on a bargain bag such as this one, but it's worth bringing attention to nonetheless.) The upshot here is that, as well constructed as this case is, it's not designed to protect our laptops from accidental drops onto hard surfaces. There simply isn't enough shock-absorbing padding. But frankly I'm not that worried about accidental drops. Rather, for my most pressing general needs--storing or transporting my laptop and keeping it free from dust, scratches, dents and the like--this AmazonBasics bag really fits the bill. It's easy to carry, and it's easy (and quick) to access your laptop. I'm VERY happy with it, would buy another one without hesitation, and I highly recommend it! Finally, my goal as a reviewer is always to try and help others make better informed decisions about potential Amazon products they may be considering. Toward that end, I hope in some small way that you may have found this helpful. Thanks for reading my review. Best of luck with your shopping!

I love this bag. It was affordable, and it has plenty of compartments to store my cords and portable drives. It is fun to be able to get work done at coffee shops and theme parks etc...

For 12.4 tablet with hard case on
Size: 14 Inch, Style: 1-pack
I got this black carrying case for my tablet and it fits well inside and you have room still if you want to carry like cables or some documents and stuff. Now only thing I wish that it was better was inside padding but for the price it is still decent as I have a case on my tablet and hard one for the matter so I just needed carry bag to carry around and it would be fine for me for anyone else think it thru as padding is not very protective inside but other then that nice quality bag and feels sturdy

Great Budget Laptop Bag / Sleeve
Size: 14 Inch, Style: 1-pack
I got this bag to use as a laptop sleeve in my backpack, because I honestly don't trust cheap stuff on amazon anymore, so I got something that would likely be more sturdy, a bag instead of a sleeve. Protection is decent and the zippers, material, construction, and overall feel, don't come off as cheap at all. There could be a bit more padding, but for the quality of bag I got for the price, it's a steal. There's an outside compartment, with folder like flaps inside, where you can use this bag as a folder too. 4.5/5 product and wish there was more padding pro protection Strap is removeable to use which is nice for carrying like a suit case, or using as a sleeve in a bag
