UK Mainland ONLY. 5 pieces for sale (5 lots for sale) Works with all Aico Ei3000 series detectors. These were included in brand new detectors. I could not get a hold of detectors without the RF Modules at the time for my clients. I had to give a massive discount to my clients as everything was hardwired. Only wishing to recoup some of my money. NOTE: Please be aware! I'm not a regular seller. I work Mon-Fri. I will endeavour to dispatch the product within 0-48 Hours after sale, with tracking info. Been a while since I used eBay to sell a product so please understand (for reasons of simplicity) this sale is for 5x Modules. I have 5 packs of 5 modules for sale
