The 12V Automotive Relay Tester has garnered mixed feedback from customers, highlighting both its utility and various limitations. Many users appreciate the affordable price point and find it functional for basic testing tasks; reports of successful tests on compatible automotive relays demonstrate its effectiveness in simple scenarios. However, a significant portion of the reviews expresses dissatisfaction, particularly regarding its compatibility and durability. Customers have pointed out that the tester struggles with certain relay types, particularly those designed with diodes or shunt resistors, which serve to protect against inductive load spikes. This limitation severely hampers the tester's versatility, as it may fail to indicate proper functionality even for working relays, leading to frustration among users. Concerns about the build quality are also noted, with some describing the product as having a "cheap feel" despite it working adequately for basic needs. Moreover, the tester has been criticized for its size compatibility, with larger pin relays unable to fit, a point that could discourage potential buyers expecting a more universal tool. Overall, while the 12V Automotive Relay Tester can serve as a handy diagnostic tool under certain conditions, its effectiveness may be limited for users needing comprehensive testing capabilities. **
