This model is equipped with a quality ProBlade. Really sharp, good trimming experience. It doesn’t cut super close to the skin, it leaves a stubble 0,5 mm to 1 mm long. The blade should be regularly lubricated to maintain sharpness and work efficiently. - Versatility. The Braun BT7420 set includes all attachments that are necessary for beard trimming, creating sharp lines, thanks to the presence of the Gillette shaver you can achieve a perfect shave too. - Precise length settings. Using 2 adjustable comb attachments you are able to pick your preferred trimming length in quite precise manner, meaning 0,5 mm increments. - Waterproof. Thanks to this feature, after trimming you can conveniently rinse the whole unit under the tap. ****Not bad:** - Adjustable comb attachments. There are two of them with ranges from 1 mm to 10 mm and from 11 mm to 20 mm. They sit on the blade pretty well, maybe some minor looseness which has no impact on the usability I guess. ****Possible weak points:** - The 2 fading comb attachments. To be honest I have never found this kind of combs useful. They are available also in some home grade hair clippers. - Travel case. It is well made, sturdy, elegant, but… so small. It can house the trimmer alone and if you try to fit in the adjustable comb attachment, you’ll have a hard time… ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-04-fits-in-the-hand.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-03-ergonomy-1.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-19-gillette-shaving-razor.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-01-travel-pouch.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-22-hard-case-travel-pouch.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-20-stencil.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-21-stencil-guidelines.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-05-length-setting-dial.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-06-charging-indicator.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-07-back-sid-of-the-blade.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-08-stainless-steel-blade.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-09-detach-shaving-head.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-10-cutting-head-detached.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-11-short-adjustable-guard.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-12-guard-for-short-beard.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-13-long-adjustable-guard.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-14-guard-for-longer-beard.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-15-charging-stand.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-16-trimmer-for-details.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-17-narrow-blade.jpg) ![](https://storage.ghost.io/c/f3/d0/f3d01ea9-4d8a-4f6d-a60c-367fb5cd95e6/content/images/2025/07/braun-bt7420-18-fading-guards.jpg) ## What are users saying about the Braun BT7420? ### **Strengths** - **Sharp & Efficient Blades:** Users report the blades are exceptionally sharp, providing a clean, precise cut that often doesn't require multiple passes. - **High Versatility:** The trimmer comes with a wide array of attachments, making it suitable for various grooming tasks including beard trimming, hairstyling, and body grooming. - **Precise Length Control:** The adjustable dial for selecting trimming length is highly praised for its ease of use and ability to provide fine-tuned results. - **Long Battery Life:** Many customers are satisfied with the long-lasting battery, noting it can power through several grooming sessions on a single charge. - **Ergonomic Design:** The trimmer is considered lightweight and comfortable to hold, making it easy to maneuver during use. ### **Weaknesses** - **Plastic Construction:** The most common criticism is the predominantly plastic build, which some users feel makes the trimmer seem less premium and raises concerns about its long-term durability compared to metal-bodied competitors. - **Attachment Effectiveness:** Some users found some specific attachments, particularly the smaller detail trimmers, to be less effective than anticipated. - **Not Fully Waterproof:** While the trimmer is water-resistant and easy to clean under running water, some customers expressed a desire for a fully waterproof design that would allow for use in the shower.
