Its good stuff ,if a bit pricey when you have added in the cost of the fittings..You will see from the SWM site that there is a big choice,I have one of the smaller ones ,but others on here have the larger bags.... You will see that there are 2 fixing systems ,an ,'origional' one ( Cheaper) and a 'new' one .. Both work equally as well and are easy to use, having had both ,the older one is slightly easier to use but the newer one looks neater on the tank and it also brings the tank bag lower by about 10mm (big deal!

) which is ok but if you over fill the bag there is an increased chance of it scuffing on the tank...
