 There are currently multiple ways to approach putting together your own SlimeVR FBT solution.

+A minimum of 5 SlimeVR trackers is required for proper full-body tracking (FBT). Alternatively, you may purchase or build a single tracker exclusively for chest tracking if you want to test partial tracking without investing in a full kit. Other options, such as using phones or Joy-Cons — do exist, but tracking quality is heavily restricted by the specific device—so expect significantly worse results.

 ### 1. Buying trackers
 
 #### Fully built trackers directly from SlimeVR

-You can buy fully built trackers for pre-order at [Crowd Supply](https://www.crowdsupply.com/slimevr/slimevr-full-body-tracker). These trackers are the passion project of dedicated core members of SlimeVR, and due to chip shortages, shipping delays and the like we cannot guarantee shipping dates or turnaround time.

 ### 2. Third-Party Sellers
 
 Third-party sellers are common, with prebuilt trackers and custom commissions offered on the [SlimeVR Discord](https://discord.gg/SlimeVR) marketplace forum. Designs and specifications vary from seller to seller, so make sure to check exactly what you’re getting.
 
 As the two most important aspects of every SlimeVR Trackers are the IMU (used to measure movement) and the communication protocol (how the tracker communicates with your device), we suggest checking the [IMU comparison page](diy/imu-comparison.html) to get an idea of what to expect from any available tracker.
 
-> **Caution:** SlimeVR cannot ensure that third-party trackers meet any specific quality requirements. Please assume that purchasing from a third-party seller is comparable to buying from a small creator, and your own research into the quality of these trackers is important. We suggest checking reviews or speaking with others who have purchased from the seller. If any of your third-party trackers develop a fault, contact the seller for support. However, you may need some understanding of soldering and tracker assembly to perform repairs yourself.
