Unfortunately I can confirm. I have purchased an AES linker from TO. Bugs, glitches and pathetic customer support. I have been banned for having outragiously said on the Discord that I will buy a product from TO never again. Discord which is the only way to reach the customer support...There is alot of bad feedback on the Discord group thats for sure! Ive had one in my neo geo since March and it works great for me. Looking forward to trying the darksoft MVS in my neo25. I must admit the darksoft products are amazing! CPS2 and CPS3 user. Just wished those ultra simms would come back to surface!
In conclusion : I prefer to give my money to @Darksoft
