Better use the regular tools instead of relaying in this. Being new do not always means better. ### ⭐ great idea but absolutely not worth your time or money *by S***E on Reviewed in the United States πŸ‡ΊπŸ‡Έ on June 21, 2017* Conceptually, this product is great and was excited to try it out in hopes it provided the fidelity to net near perfect adjustments. Placing the plastic clips was very easy, as advertised but, quickly went down hill from there. First negative surprise was discovered when I had to pay to use the application, and were not talking a cheap one time charge which started off the experience on a negative note. I paid for a 7 day usage plan only to find the instructions to shift the chain to specified rings on the cassette were not clear at all. And after making several adjustments based on my interpretation of the instruction, I was in worse shape than I started. In the end, I abandoned the usage of this device and manually readjusted my settings to get me back to where i started. So, I am now the owner of a completely useless tool that I considered reselling on ebay but, couldn't feel good about myself taking any money for this product. Before spending any money on this, I would suggest look at youtube videos on setting up your upper/lower limits and using barrel adjuster to optimize your indexing - cheaper, easier, and you wouldn't have wasted your money. ### ⭐ Take your local LBS a six pack and learn the proper way! *by M***T on Reviewed in the United States πŸ‡ΊπŸ‡Έ on August 31, 2016* Save yourself the time and money! Being a gadget guy and seeing that the reviews were decent I wanted to give the Otto Tuning system a try. First you have to pay for a subscription to access the full capabilities of the the product. Secondly it just doesn't work well. It uses the front camera which is very light sensitive and has a hard time actually capturing the data points. Any shadows on the data points makes for a difficult time. Once it does take readings then the recommendations are not always the best. Ex. 4 turns CW then follows up with 6 turns CCW.......How does this make any sense. Haha!I tried the product on both a 1x10 Mountain Bike (XT Shadow) and a 2x10 Road Bike (Dura-Ace). I received "OK" results on the MB but fine tuned after the fact. The end results for the roadie where awful!!!At the end of the day support your local LBS or better yet have them teach you how to properly tune your bike! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/21361946-otto-tuning-system-10-11-speed-cassette](https://www.desertcart.pt/products/21361946-otto-tuning-system-10-11-speed-cassette) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
