Very convenient. You can start the engine while staying at home. It's great in the summer, but especially good in the winter; if you turn on the air conditioner, the temperature will be comfortable when you get in the car. This is a WES250 remote starter with a wireless engine start function and a turbo timer. I removed it because I sold the car. It was working normally until I removed it. (I will also include the broken seal antenna in the shipment) ⭕️⭕️The seal antenna broke when I peeled it off⭕️ However, the antenna connection cord is quite long, so it might still function as an antenna, but I haven't confirmed this. Model name: WES250 - Function: Wireless engine start (Engine start time can be set) - Timer function: With turbo timer - Accessories: Remote control, wiring set - Instruction manual: With instruction manual Please understand that this is a used item, not a new one. Thank you for looking.
