I have mixed feelings about this one. On one hand, it's incredibly soft and the giraffe design is just precious for photos. However, the sizing is way off—I ordered the 0-9 months and it barely fits my 5 month old who is average size. It's also a bit thinner than the robes you get at more expensive stores, but I guess you get what you pay for. It's okay, just order a size up.

The filter itself is great and fits my Corolla perfectly, but the pricing is getting a bit ridiculous lately. It does the job and gives you the peace of mind for the warranty, which is the main reason I buy it. However, the packaging was a bit crushed when it arrived, even though the filter was fine. Good product, but the value proposition is starting to shrink compared to high-end WIX filters.

Waste of money tbh. My husky literally just barks right through the sound like it’s not even there. Maybe it works for smaller dogs but it did nothing for mine. Returning it tomorrow.

Bought this for my 4yo's birthday and he's obsessed. He's been building "spaceships" all morning. For the price, you really can't beat the amount of pieces you get. Some of the blocks are a little stiff to snap together at first, but they loosen up after a few uses. Great buy!

This is my third Kipling case and the metallic finish on this one is gorgeous. It holds way more than 100 pens if you don't use all the elastic loops for every single pen. I use the bottom section for my bulkier markers and the top for my fine liners. It’s a bit bulky for a small backpack, but if you carry a lot of supplies like I do for bullet journaling, it’s a lifesaver. Plus the little monkey keychain is a classic touch.
