The performance price is reasonable.
I bought two bags, and both had quality issues. The Navy Transporter Deluxe Backpack was weak at the straps and started falling apart. I contacted SpiralUK, and they were outstanding! Evri stole the first replacement, but the second was successfully delivered. They sent me a Black Portland Backpack, which is an insane bag!! I love the look and feel. I can see that there are some subtle upgrades and changes which will make the bag last significantly longer. This company is relatively new, and I like where they're going. It takes time to perfect a product.
Advice to new buyers: these are “office” bags ideal for laptops and stationary accessories. They’re not meant to carry Kilos of gear or be overloaded.
