there's no more distributor in Singapore but I'm truly grateful that robotshop exists and have worldwide/international shipping services. keep it up guys! their service is excellent i can't deny that and never let me down if i have issues with their product. really good customer service is so much better than buying a brand new robot! its worth what I'm paying for. as for this wire harness, at first sight i don't have confident that i can fix it but i follow the instructions given and volla.. i managed to do it like 1 hour to complete the installation. its about a week now and it doesn't have any light blinking issues anymore. i noticed that it is now working well with the upgrade version too and in my previous review my litter robot upgrade circuit board had let me down but now it fix everything with this wire harness. i would like to take it back what i said in previous review. for those who had issues like mine, i would highly recommend to buy this wire. this will change the unit feel like into a brand new. thanks robotshop team. you guys are fantastic
