From Vintage to classy to contemporary - True Tune tuning keys cover a wide range of applications. Drop-in ready for most platforms and made from high quality materials and components, we have engineered these keys to offer pro-level performance with a high-end look and feel!
Open Gear 3x3
Our True-Tune Open Gear tuning keys offer a sleek and traditional look made to compliment any high-end guitar! The higher 18:1 gear ratio and tighter string post offer more accurate and stable tuning, and the high-quality steel worm gear with its nylon washers ensure a smoother high-end feel. This key features a collar on the base plate of the key surrounding the string post. This ensures the post sits properly in the headstock, centering it with the included bushings to help eliminate friction between the bushing and string post and allowing for smoother tuning and improves the over-all longevity of the key. Whereas some other open gear keys require a two-step hole (smaller hole for the post and larger hole for the bushing) to be drilled, the True-Tune open gear keys require only one size (8.5mm) hole to be drilled the in headstock for both the post collar and bushing. Whether upgrading your existing keys or installing them onto a new build, the True Tune Open Gear tuners were made to give your guitar a high-end look with stable and accurate tuning!

Cleans pretty good, and the app is great.
Color: White
Have 2 cats and this helps manage the hair. The lidar works great, it won't drive off a balcony or down stairs, and can map rooms pretty quickly. Obstacle avoidance is usually good, but it clearly cannot detect wires. If you have a bunch of cords under a desk or TV stand or something, it will tangle itself up in the cords.
Which is where the app comes in, you can set areas where it is not allowed to go. Just didn't allow it where my cords are piled up and have had no issues since. You can also set it to not get too close to a balcony or staircase, which is good peace of mind, even though the lidar seems to do fine with that. You can also have multiple "map layouts" if you have a multi story house, and switch between them in the app. The app is very good.
The dustbin isn't huge (by nature of the size of the robot), so if you have particularly hairy carpets it'll probably take a couple vacuums to really get all the hair out.

My everyday helper
Color: Black
My house is 100% hardwood with throw rugs in various places. Two levels. Two minimally shedding dogs until their hair is very long. But they do still have hair fall. I also have a gravel driveway and lots of kids and grandkids. I purchased several vacuums prior to this one trying to figure out a solution. I do still love my Oreck upright and find this robo vac its perfect companion. I have had the Roborock Q10 for 4 months now. There have been times when I definitely had to pay attention to it and clean sensors or re-pair to the WiFi. (When I changed WiFi password) And as you can see in my video, I still have to vacuum the rugs. I actually have the vacuum programmed to avoid the thicker rug under my kitchen table. She (the vacuum we named Crystal) got stuck a couple of times between the legs of my kitchen chairs. So I just changed her parameters to avoid the area. I also have my mother’s room off limits in case she leaves her door open. If Crystal finds an open door, she will absolutely go in to do her job. As a matter of fact, she went right out the front door once when someone left it open.
My mom and Crystal have a fun “relationship” mom texts me whenever she’s doing something or says, “returning to dock”. She swears she follows her around and giggles at her.
I have stopped using the mop. The mopping pad has to be rinsed prior to each use (to wet it) and after if you’re good. And the bucket for water is very small. The floors are so clean of debris that I mop less often now anyway so I don’t mind. However, I realize I don’t need the mop for a future purchase. I suppose if I decide to use it once in a while, it’s still worth having.
I did have to find the bags and ordered separately. This unit comes with one bag. They were inexpensive and super easy to change out.
The feeling of coming home with no debris along the baseboards is life changing. Clean floors are a must for every home in my opinion. My brain just works better when my floors are clean.
We view Crystal as a member of the family now and treat her with great respect. We keep her clean and pay attention when she’s alerting us of anything.
Even though she could do two floors, (mapping capacity) I am considering purchasing a second one for the basement. I can’t imagine having to carry her back up and down the stairs when she needs to empty or charge.
I have suggested to many of my friends to purchase this for their families.
I do also have several low pile rugs that Crystal vacuums and does an amazing job. But I would think anything high pile or shaggy might be difficult for her.
Buy it, name it, keep it clean, and enjoy clean floors with minimal effort. 10/10 even with the minimal maintenance. She is such a hard little worker.

User friendly and I highly recommend
Color: White
I recently purchased the Manvins Robot Vacuum and Mop Combo with WiFi capabilities, and it has been a game-changer for keeping my home clean. The setup was incredibly easy, and I was able to connect it to my smartphone in minutes using the app. Once connected, I can schedule cleaning sessions, monitor progress, and control the vacuum and mop remotely, which is super convenient.
The vacuum picks up dust, pet hair, and debris effortlessly, even from carpets. The mop function is a nice bonus, and it does a great job of leaving floors streak-free. I was surprised at how well it handled both tasks simultaneously, and it’s great to not have to worry about switching between modes
The WiFi feature really shines when I’m away from home. I can activate the cleaning process from anywhere, and it returns to its charging station when it’s done. It even maps out my home as it cleans, ensuring that it doesn’t miss any spots.
Overall, this robot vacuum and mop combo has made cleaning much more efficient, and I love how easy it is to keep my floors spotless with minimal effort. Highly recommend it for anyone looking for a smart, reliable cleaning solution!

Excellent vacuum!!
Color: White
This is a hard working little robot. It cleans dirt and debris so easily and even gets the Arizona dust that accumulates everyday. I have a cat the sheds and 4 boys plus my husband and this vacuum works like a champ. I haven’t tried the mop feature yet because I just haven’t sat down and read the directions. I’ll update when I try that feature out. I love that it can go under my furniture and climb up rugs, even my cat scratch boards. I 100% recommend this vacuum. It has changed my house keeping routine and saves me a ton of time. I absolutely love it and you can’t beat the price!

Pleasantly surprised.
Color: White, Color: White
Based on the price I wasn't expecting much but boy was I wrong. I'm so impressed and thrilled with this purchase. I have a long haired Maine Coon and it picked up so much fur. It picked up thread, small pieces of yarn and feathers from my pillows. I watched the long front brushes pull dust and dirt out from under spaces that my regular vacuum would never get without moving things. I have carpet, hardwood, throw rugs and even a long shag throw by my bed that it maneuvered over mostly easily. I helped it over one or two transitions but it never got stuck. Just turned and kept going. The mop worked great. Only concern is that it only uses water so it's not a deep clean but the pad was dirty and once it dried I threw it into the wash. Definitely will use it in between a deeper cleans making cleaning a whole lot easier. With a cat shredding the carpet on a scratching post and all of his fur I was shocked how packed the dirt cup was and how great the house looked with all the little bits of scratching pole, oh yeah and card board scratching pad cleaned up so easily. I highly recommend. The cat thinks it's a cat toy so he kept starting it up. I had to cover it to protect it from the cat. It now lives under it's very own plastic bin. 🙂
