First of all, I'd like to say that we own other Skip Hop items and think their products are typically excellent quality and very functional. This made me more comfortable to spend twice as much on these tiles than other brands. They're made of durable foam and I like the option for various patterns to suit your decor. However, because there are gaps between the tiles, my 9 month old is easily able (and eager) to pull them apart and chew on the them. From that perspective, I'm not happy with these for baby's use even though they're marketed for this purpose. These tiles become an activity in themselves rather than a practical surface for other activities. They wouldn't likely hold my baby's interest for long if they weren't easy for him to separate. I also wouldn't have to reassemble them so often in order to keep baby's play area in tact. We've set some heavier items on them and they haven't dented, though baby was able to leave a few teeth marks on a couple tiles. Some tiles also had holes on the underside straight out of the package. This looks like a manufacturing defect. Time will tell if this will effect how well they survive daily use. Overall, this is a decent product and definitely better quality than what you'll find at WalMart. I usually don't mind spending more for better quality and performance either. But, I'm not sure these are worth the price. I chose these over cheaper options because they blend nicely with our decor, and I've also grown to trust Skip Hop products from prior use. This product has been my first disappointment for the reasons mentioned. Would I buy these again? Not for baby's use, but perhaps for toddlers. For now, I plan to set these aside until baby is older and less interested in pulling things apart and chewing on them.
