They have excellent grip on 97% of wet surfaces. Took me about 7 mins to assemble and if I had to make 1 complaint it would be that the strap in which you mount this stand to the wall is a little flimsy. I would say that this is a good case for the G305. Cheaper than the Fitflop shop with discount. Returning for a larger size, hopefully they fit. The previous owner had installed a uselessly configured, ugly wire organizer. But I have been won over 100%. The Large size will fit over Bluetooth headphones, dont get the Small ones since those are sized for standard-size wired headphones. Recommend for womens size 6 as opposed to what is being sold as womens on here. Very pretty.
