The 8PCS TT Motor DC Electric Gear Motor is a popular choice for DIY enthusiasts looking to build their own smart car robot or aircraft. The overall customer experience with this product has been mixed, with some positives and negatives reported. One of the standout features of these motors is the housing that encases the entire motor, unlike the yellow plastic gear ones. This design choice has been appreciated by customers, as it adds a layer of protection and durability to the motors. However, there are a few drawbacks to be aware of. Some customers have reported a noticeable amount of gear noise when the motors are in use. While this is to be expected to some extent, it may be more pronounced than desired for some users. Additionally, a significant number of customers have received motors with a faulty or "crunchy" gearbox. One out of every four motors is said to have an acceptable non-crunchy gearbox, while the remaining three were deemed unusable. This quality control issue is a major concern for potential buyers and should be taken into Consideration. On a positive note, the motors are reported to have plenty of torque and perform well once the gearbox issue is resolved. Customers have also appreciated the quick delivery time and lack of other problems with the motors. In conclusion, the 8PCS TT Motor DC Electric Gear Motor is a decent choice for those seeking motors for DIY projects. However, the gearbox quality control issue and gear noise may be off-putting for some users.
