I think the kids would love it. The spray in liner is great, but I haul the kids up to the neighborhood pool, and I do get complaints about their knees and whatnot. Not to mention the rubber mat would probably keep my normal equipment hauls in place a little better.
Seems like overkill to me. I have the factory spray in and it serves its role just fine. If I were to add something more to it, it would likely be a bed mat over the liner instead.
I was skeptical about the lack of physical buttons, but I think they did it about as well as they could have. I’ve been very pleasantly surprised. Love the screen in general!
