Been using this since I got my bike and been using it for every ride. Magnet is strong Bag is bigger then it looks, able to store a folded deliveroo raincoat in. Able to put your emergency tools in (no joke) Great to put in your wallet, passport, security pass, tissue paper, extremely accessible. Great going in and out of customs or checkpoints like Jurong island checkpoints Able to put phone with GPS on the front, good for riders who don't know the roads well and require assistance navigating. Waterproof af. I can ride 30mins plus in heavy rain. Skid and fell. The bag is moist inside but my phone, Nintendo 3ds and wallet is fine with no scratches, zero damage.
