Not good they fit as they should however no mater how tight you secure them they spin and at times do not hold the item which drops off.
We have had the bl-980 for about two years. It is a great tool for setting stone and precast steps that we cant use our Pave tool suction equipment on due to irregular surfaces. We have gone through our fare share of pads due to rough face rock steps. These new pads look to be more durable than the original ones. All of these tools have saved on time and prevented injuries we have had in the past with no damage to the material. Although there is a cost associated with this equipment you will wonder how you lived without it once you start using it.
The main reason we need replacement pads for the 980 is because we use it so often! Thanks for the safe and simple design!
