I would recommend it to everyone.

Dear Melanie
Yes, the EtchMaster is excellent. It is by far the best sandblaster I have used (previous was Ronvig). The powder spray is precise and scatter is virtually none, keeping the rest of the mouth ‘clean’. It is easy to use all except for removing the used capsules. Pulling back the locking ring is stiff and tricky with one hand and then trying to pull out the capsule with the other hand is difficult. Therefore, I give it 9 out of 10; it looses the one point because of the removal problems of the capsule. However, I would recommend it to everyone.
Regards,
Paul
