Bullet - to pinpoint areas, release trigger points
Fork - to work around a specific muscle group(s)
Ball - greater surface area, best attachment to start with
Flat- smaller surface area, great to use on more dense muscle groups
I have purchased four pleno massagers, for personal use and for gifts. I continue to be very impressed with the customer service I get. Heavy usage wore out several of the tips. A quick email, and I was able to purchase replacements at a very reasonable price. They arrived quickly and without any problems. I continue to recommend Pleno products to friends and family.
Really like this set. Works great. Fast shipping.
