Sound Devices MX-8AA Battery Sled Accessory for the MixPre-3 & MixPre-6 Audio Recorders

### Sound Devices MX-8AA Battery Sled The Sound Devices MX-8AA Battery Sled accessory is designed to enhance the power capabilities of the MixPre-3 and MixPre-6 audio recorders by doubling the battery supply. However, customer feedback reveals a series of shortcomings that significantly detract from the overall user experience. Many users have encountered issues with stability, citing that the sled has excessive play when connected to the MixPre-10T, prompting the need for makeshift solutions such as using gaffers tape to secure the connection. This instability leads to concerns about potential power disconnection during crucial recording sessions, which can be a deal breaker for professionals on set. Moreover, the design and practicality of the sled have drawn criticism for being poorly engineered and overly cumbersome. Users report a frustrating experience when attempting to insert and remove batteries, likening it to a battle requiring a significant amount of force. This has led to suggestions that the Construction seems out of proportion to its price, which many believe should be significantly lower given the quality of the materials used—described by some as "cheap flexible plastic." While the MX-8AA serves its primary function of increasing battery capacity, the collective user sentiment emphasizes that the frustrations tied to its design and usability overshadow its benefits. For those in need of a reliable and efficient battery solution, alternatives like the Sony rechargeable sled are recommended due to their superior design and functionality. ### Pros and Cons **
