I was surprised to find no reviews or information on the Wego roof box, but I bought one anyway, along with the Modula roof bar kit, and I'm very impressed with both. The roof box is sleek, the dual side opening is great, and it looks fantastic on my car. Space is huge at 500 litres, but when putting in my biggest suitcase I had to zip up the expanders otherwise it was too just a little too tall for the box. Easy to fit, and the jaws secure the box to the roof bars in seconds with a positive 'click', and didn't come loose at all on my test drive. Once fitted the box sits nice and low on the roof, clearing the shark-fin aerial on my car, but creating virtually no wind noise, even at 70mph on a blustery day. MPG on my car on a 20 mile trial journey on country lanes wasn't really affected, and you barely notice the roof box is fitted. Very glad I bought this over the far more expensive and bulky boxes available, I just wish I had washed my car and removed the protective film on the box before I took the photos!
