Have been using this for about two months perfectly, every day I make 25-50 calls. Another great feature with Crocs in general is that they weigh almost nothing. The most helpful and insightful pieces to this book are the quotes from the "2001" co-producer Mel-Man. I requested a replacement but the replacement is doing the same exact thing. This t-track system will work well for holding pieces to route with the sled. That being said, once you open these up, dont judge them until you adjust the EQ settings. I cannot, in good conscience recommend these from an aesthetic standpoint - but in terms of functionality and comfort, my dad loves them. Good from far but far from good. I set two of them up high on a wall with a little wheel overlap between both to pack the bikes in a bit tighter. Bit overpriced if imported though as it?s not available on Amazon India.
