About BlueStar A1
BlueStar A1 uses pre-tensioned tensor sponge with a catapult effect and relatively low dwell and a grippy, non-tacky topsheet typical of European tensors. Manufacturer sponge hardness is 50° (Tensor); a cut sheet is about 49 g. Factory sponge thicknesses: 1.8, 1.9, 2.0, 2.1, MAX. Sold with topsheet in Black and Blue and Red; sponge in blue.
On the TableTennisReview 0–100 index the Combined figures are speed 95, spin 91 and control 76 (official mapping 94 / 90 / 75). That is a high-speed inverted profile for power-offensive play from mid-distance — heavy loops and finishing hits. Hardness, weight and thickness above are factory facts — not lab tests.
Community score 8.8 / 10 from 160 reviews. Indicative European street price €46. Compare BlueStar A1 with other Donic BlueStar and inverted rubbers on the same scale, or open the catalogue filters for OFF+ inverted sheets.

Factory thicknesses
Factory sponge thicknesses sold in Europe: 1.8, 1.9, 2.0, 2.1, MAX. These are shopping facts — Combined speed / spin / control on this page do not change with thickness.
- 1.8
- 1.9
- 2.0
- 2.1
- MAX
- 1.8
- Thinner inverted sponge. Allround and first-upgrade backhands live here more often than attacking forehands.
- 1.9
- The usual club backhand thickness on inverted tensors. A bit more control, a bit less catapult than 2.1 / MAX.
- 2.0
- Mid-thick. Common on the backhand when MAX felt lively, or as a two-wing compromise.
- 2.1
- Still a thick attacking sponge. A small step down from MAX on some tensors — shops treat it as the other FH thickness, not a control sheet.
- MAX
- Thickest factory sponge. Most catapult on a tensor; the usual attacking forehand. Combined figures on this page are for the SKU, not a separate MAX score.
