Which Valve Bypass Controller? (UK)

Hi all,

I am trying to figure out which valve controller to buy. There's a wide range of prices but they all do pretty much the same thing. I am going to self-fit so am only concerned about the hardware.

• ASR ( £260) https://asr-component.de/Ferrari-F12-Klappensteuerung-RX1/A-001-008-14
• Forza (£426) https://www.supertweaks.com/ferrari/ferrari-exhaust-bypass/ferrari-f12-exhaust-bypass-valve-controller-remote-kit
• CarGraphic (£390) https://www.cargraphic.de/en/your-vehicle/for-ferrari/f12/v12/cargraphic-tuning-program-for-ferrari-f12-v12/for-ferrari-f12-v12-cargraphic-sport-exhaust-systems/cargraphic-valve-control-for-ferrari-f12-v12/exflaprcfer1/
• Capristo (£531) https://www.scuderiacarparts.com/aftermarket/ferrari/488/exhaust-remote-kit_15343?utm_medium=cpc&utm_source=google&utm_campaign=Google_Search_Generic_UK_AM_Units_Capristo_EXA

Forza looks like the best build quality in terms of the cables. Capristo seems to be the most well know (but also the most expensive). CarGraphcs and ASR are much the same (would not be surprised if they are the same). At the moment my mind is split between ASR, or spend the extra for the Forza build quality. I am not sure how much water is going to find the inside of the rear bumper?

Would love some advice, especially if you have installed yourself?
