What I like about the genesis is the way you slide the top on so no risk of scratching by sliding wedges in and I like the way you remove them with the gun so no knocking them off Andy no danger of chipping a tile. The problems I see are the gun, at £50 a pop you expect it to be a nice tool but on this job I’ve been through 4 guns, it got to a point that genesis sent me 4 at once! They admitted there has been problems. The tops, a lot of them are fine but some are too loose and you can torque them up because they don’t grip the teeth on the base. The bases have a significant curve to them which can increase the feeling of a tile being bedded when it isn’t, and it also makes it hard to leave a clip in for the next day as you slide it in, the angle it sits at means it doesn’t sit tight to the tile, if that makes sense. Also, the price, very expensive, and if your paying a premium price you want a premium product don’t you.
