I was trepidatious about spending more than ten dollars on a sponge but a friend pointed out its Safety gear for kayaking so I bit the bullet and ordered it. I must say that it has been worth the expense. In salt water a dollar store sponge wouldn't have held up and this Skwoosh sponge really soaks up the water! I was and still am amazed at how well this Skwoosh sponge really works, it takes on a huge amount of water and drys my kayak cockpit down to the last drop. I think the tide actually rose a little when I was done ringing it out, lol. It seems to be quite durable so far as well.
I have to recommend this Skwoosh Bilge Sponge highly and add that I have never seen anything like it. Well worth the money.
