D'AddarioViolin Rosin Guard with Dark Rosin - Rosin for Violin, Cello, Viola, Double Bass - Shock Absorbent - Magnetic Attachment - Easy Grip - Dishwasher Safe

I bought this 18 month ago and my daughter 9 yo still has it. Previously I had to buy one per month because it was constantly shattering. This design is perfect for children. It's the toughest and most durable rosin that withstood many drops.

Easy to use

I've been a student of the cello for two years and bought three cakes of dark rosin in that time; this one, Pirastro 9011 Good Quality Rosin Specially Formulated for Cello, and d'Addario Kaplan Premium Rosin with Case - Dark. I bought all of them from Amazon and this one was by far the cheapest. The UK climate is not particularly extreme and frankly I find it hard to notice much difference in use between the performance of this rosin and the others, though this one may be marginally less sticky. The chief advantage of this block of rosin is its shape, which is much more convenient to use than the round cake shape that the other two rosins come in. Also the round cakes have a tendency to fracture on the edges as they are used, scattering tiny shards of rosin across the carpet. So far this block has not fractured at all. The matchbox style packaging is also extremely convenient. The Pirastro rosin has to be wrapped up in an attached cloth and tucked away into a small box for transport or storage. The d'Addario plastic case with a clip-lock lid is handy but as time has passed the rosin block tends increasingly to jam and get harder to turn. I use rosin pretty freely but although there is residue on my strings after practice, there's very little accumulation on the surface of the cello. So this is certainly my rosin of choice and the one I'll be returning to.

This has a decent sound in the strings and I am very happy with it ☺️👍🏻

Arrived fast and does its job

Makes life easier not 100% sure about strength of rosin for double bass though.

Excellent rosin. Used for cello.

Delivered broken but is good quality
