Introducing BackZone 35 (250-1903-BZ35), Rostra’s latest addition to our comprehensive line of vehicle parking assistance systems. Designed around the durable components that comprise our BackZone 35 system, BackZone 35 expands the usefulness of that system by adding an extra 10 feet to the sensor extension harness and a more powerful control module. Key features of this system include the following:

Smaller Audible/Visual Display
Compared to Rostra’s standard BackZone Plus and FrontZone parking assistance systems, the BackZone 35 includes a dashboard/visor mount display with a smaller overall footprint designed to more seamlessly blend into a vehicle’s interior.

35-Foot Truck Harness
BackZone 35 sensor-to-module wire harnessUltrasonic parking assistance systems typically require the use of harness extensions when being installed onto light or heavy-duty trucks. These extensions can introduce multiple points of failure and interference. That changes with BackZone 35. Each BackZone 35 system includes a weather-proof 35’ harness designed to connect the four bumper-mounted ultrasonic sensors to the BackZone control module in a single run.

BackZone 35 Control Module
BackZone 35 contorl module with advanced object detectionThe BackZone 35 control module is specific to this particular parking assistance system and includes an internal electronics redesign necessary to transmit interference-free signals from the bumper-mounted ultrasonic sensors along the 35-foot harness.

Perfect for Bulletproof Coffee, Shakes, and Daily Use
I have been using the previous FoodVille frother since 2024 and I still rely on it, but the MF06 is definitely a real upgrade. The build quality is better, it is simple to use, and the sturdier attachments feel more durable. I love the single‑button variable speed control! The new digital display is another nice improvement, and I find the charge lasts longer, which by the way, it charges by USB so no batteries needed. I use it daily for bulletproof coffee, protein shakes, and for mixing other supplements. Customer service has been excellent and always responsive. I am very happy with this purchase. For the price and performance, it is an excellent choice!

I love it!
Color: Black, Size: Rechargeable
This thing works great! It holds a charge for a long time. I love that it has different attachments. I use it mainly for mixing powder into my drinks. It is very powerful. The speed is adjustable too. It feels good to hold too. It lights up when you squeeze the trigger and when it starts losing charge, the light bar gets shorter. I highly recommend it.

Perfect all-around frother, stand keeps it nice and neat on the counter within easy reach.
Color: Black, Size: Rechargeable
Rechargeable, lightweight, variable speeds and optional whisks all make this the perfect item for your kitchen. You can quickly froth milk for your coffees, whip a small batch of whip cream, and even make mug cakes with the hook attachment. The price is very compatible with the competitors, but the ease of use makes this a top choice. The variable speeds makes it much better to control than the push button ones. When you let go of the pressure switch it turns off, no need for a dedicated on-off switch. Having the pressure switch on the top makes it extremely easy to use! It fits very comfortably in the hand and with the metal stand, looks quite nice on the counter, ready to use at any time. I highly recommend this InstaWhisk!

Great product from a great company
Color: Black, Size: Rechargeable
This product works very well. There are several other whips to use also. I absolutely love the cream it makes and that is important so I can enjoy my morning coffee. I used this whisk for quite a while then all of a sudden it stopped working. I wrote to the company to explain. A few days later they sent me a beans new whisk. GREAT item and great company to work with.

Great Frother - almost too powerful
Color: Black, Size: Rechargeable
I’ve been using the Tyohur InstaWhisk milk frother for a while now, and overall I really like it—but I wouldn’t quite give it 5 stars, and honestly it’s because it might be a little too powerful for its own good. First, the positives: this frother does an amazing job. The single-button control is super easy to use, and I love that you can adjust the speed just by how much pressure you apply. It feels very intuitive, and you can really dial in the exact texture you want. Whether I’m making a latte or mixing something thicker like a protein drink, it handles everything smoothly. The performance is seriously impressive. On the lower speeds, it creates nice, silky foam, and when you turn it up, it’s incredibly fast—like café-quality foam in seconds. High-speed frothers like this are designed to create rich foam very quickly, and this one definitely delivers on that promise That said, the power is also what knocks it down a star for me. If you’re not careful (especially when using higher speeds), it can splash pretty easily. The product description says it’s designed to prevent mess with stable low-RPM operation, and that’s true if you stay on the lower settings—but once you ramp it up, you really need to keep the whisk fully submerged or start slow, or it can send milk flying out of the container
