Prime Line

Welcome to the Prime Club. 

Prime Line Turbines express the essence of sophisticated dentistry. Designed and engineered to help you create preparations like never before. Pushing the limits of aerodynamics even further, we mastered the airflow over the Prime Line's AeroAcoustic blade.
More power, better sound, spectacular control. Built for the pro user who demands best-in-class.

AeroAcoustic blade
Quietly precise, round for round.
Ultimate blend of supreme performance:

MK-dent introduces its outstanding premium cartridge. The AeroAcoustic Prime Blade, honed to create 25 W (at 350k rpm) of steady power. Thanks to proprietary laser balancing technology, the Prime Line Turbines run smoothly and vibration-free at max. 55 dB (A).


Next-gen carbide bur guide
Perfect concentricity, unrivaled retention force.

The world of drilling would not be the same without carbide.
Pressed with 12 tons of pressure and heated to 1,500 °C, carbide is so hard, industrial diamond — the world’s hardest material — is used to grind it. Perfect concentricity and unrivaled 40 N of retention force improve long-term precision during operations.


Reverse flow protection
Endurance from start to finish line.

The non-return system for reverse flow protection has been part of the Prime Line from the beginning. It’s an entire system fabricated onto a single component, vastly minimizing the entry of particles and contaminants into the head. With endurance from start to finish line, it is designed for optimized cleanability.

Ceramic Bearings
Refined formula, silent rotations.

Dental bearings face the most extreme conditions:
Particularly high rounds per minute, attacks by superheated steam or various cleaning fluids. Paired with a corrosion-resistant cage as well as the remarkably refined formula of the lubricant, the ceramic balls will have a long journey ahead of them.

Automatic Pressure Regulation
Adjust to any situation.

Achieving the right balance between strength and durability is the engineer‘s dream. The pressure regulation can adjust to virtually any situation. It has been carefully sculpted to regulate the airflow and ensure a constant level of pressure. This enhances gradually the lifetime of the cartridge and bearings.

Quality Control Issues
I want to like this dock, I really do. I purchased it with the intention of using it as a hub for my phone + usb-c external display. The pass-through charging never worked on this dock. Tried multiple cords and tested the dock with nothing plugged into any of the USB ports -- all of the power disappears somewhere onto the hub and the actual charge rate on my phone slows to a trickle. With nothing connected, it estimates >24hrs to charge from 30% to full. The plus side is that the usb ports do work, though the usb-c display went from 100% reliability to <50% within a few months of purchase. Extremely frustrating.

This is the one, buy it for DeX!
Looking for a compact USB hub to connect your laptop or Samsung DeX capable device? Buy this one! I've tried multiple similar items from name brands, and they work fine as a USB and port hub, but this one is able to support power delivery and display data through a single (capable) USB-c cable. I assume because it is noted to be capable of some combo of USB 3.2, PD 3.0 pass through and DP 1.4 alt mode. I'm not quite sure which one(s) make it possible, but it works for an HP Spectre laptop and Galaxy phone. Only improvement suggestion is to add an additional 10gb capable USB-C port in place of the three USB-A ports, but that's being super picky. Thanks StarTech for building another unique solution for connectivity challenges.

Usb-c passthrough started failing about a year into ownership.
This had the potential to be the perfect accessory for my M4 MacBook Air. It is very difficult to find dongles like this that support display passthrough via usb-c (meaning that if you have a usb-c display you can connect it to this and use the display). When it did work, I was able to power a triple monitor setup with my 2 port Macbook Air (with one display being driven by a displaylink adapter). If this product had continued to work as advertised, is would be a 5 star review. But after maybe a year of VERY sporadic use (I use this maybe once a week because my MacBook Air is not often docked) the usb-c passthrough is already failing. On a display I use every day with a different machine (a 16" MBP that has enough ports to not need any adapters) and the display and cable work perfectly fine there so I can only assume that it is this specific adapter which is failing. If I insert the connector several times, sometimes I can get it to work but my success rate just keeps dropping. There was no other reason to spend this much on an adapter that without usb-c passthrough offers just 3 usb-a ports like most much cheaper adapters. So to say I am disappointed is an understatement.

Expensive, but it works
The good parts: Yup, this works with DP alt mode, single cable use works for most devices I tried (steam deck, laptop, odin mini 2) even without the hub powered through the power in on the hub, I even got it working without external power to either the hub or my small usb-c monitor. However, some devices like my phone likely didn't give enough power for it to work without another power source. On my phone it worked for some usb devices without external power, but the dp alt mode didn't do work. DP alt on my phone works just fine with external power connected to the hub. Powering it with a small but powerful power bank worked fine, but lower power power banks might not keep up especially if the monitor isn't getting it's own power. It only takes a watt or two of power for the hub itself from some quick and dirty measurements charging my laptop through the pd-in on the hub. As for the rest of it, the three usb 3 ports means you should be enough to get by for any use case, though you may need more dongles or adapters to get the type of connections you need, but quite usable as-is for a lot of purposes. Basically it does what it says, there really is no other hub currently that can do pd alt mode, only big docks which need power supplies. The ok parts: *When it isn't powered* I noticed that with a monitor already plugged in, plugging it into a device would lead to the monitor not being initialized. But plugging the hub into the device first before connecting the monitor worked. No issue when it was powered. You can use this to get display out and charge with a Nintendo switch, but if it's not powered through the pd-in it probably wont switch to TV mode and output video, not sure if that's because of power or software reasons. This is a nitpick, but if you care about the feel or aesthetic it's noticeably bland. The case is plastic and there seems to be no weighting on the inside, it's very light, which can feel cheap but it's not like adding weights would functionally make it better, the case also has a bit of a harsh feeling where it's joined, but it does feel solid and durable enough. It's clearly function over form, just barely meets the minimum bar imo. The bad part: You already saw, but the price is a bit steep for a hub (at $80). I'd love to see it at 60 or even 40 instead, I hope more similar hubs pop up for competition. In summary: It does what it says, if you know you want this and what it is then get it, I feel like it shouldn't cost this much, but it's quite usable and for now it's the only option for a DP alt mode hub. Minus a half star each for subpar presentation and price 4/5

Great for AR Glasses
This USB hub has been great for me! It's taken me so long to finally find a stable setup to allow using my XREAL Air glasses, peripherals, and charger at the same time. I've used this both with my phone and ROG Ally and I have not once had a problem. I even found that my ROG Ally manages to get the full supported PD of 65W, as long as I power the hub with a 100W PD charger. That said though, using a 65W PD charger is still more than adequate to charge the device while using various peripherals and a USB-C display. Previously I used USB-C hubs with HDMI out and another device to merge the HDMI output with a USB-A connection into a single USB-C cable that I use for my AR glasses. This setup worked, but would increasingly stutter/freeze the longer I used it forcing me to constantly unplug and re-plug it in. In trying to find a solution that didn't split and merge back the display signal with USB data/power, this hub was the only one I found that wasn't thunderbolt 3/4. I will say that I wish the cable to the host device was either longer and less rigid, or shorter with an optional extension cable. An ethernet port would have also been nice, but using up one of the USB-A ports with a USB ethernet adapter works if needed. Plus, if I wanted ethernet with it, then a dock would probably have been a better option over a hub anyway.
