You realize that thousands of people purchased Synapse X are 100% satisifed. Sk8r is garbage compared to Synapse X's support in execution (supporting EVERY script), free obfuscation after purchasing. The amazing 24/7 support who aren't sarcastic. The full support book, amazing script hub and the update times.
20$ is 100% worth it as Minecraft is coming soon to Synapse X.
TD;LR : You are just mad that you can't afford Synapse X so you wanna send bad reviews their way so you can be using "the best exploit"
