I am a solo performer and I have just purchased my first IEM system (T.Bone) and wanted a cleaner for the buds (Shure SE215). I searched the auld WWW and found this to be the best suited and most affordable for my needs.
I have only used it a couple of times and it works. My only quibble is that it clearly states a brush is included. In my case at least, no brush was included. A minor matter as brushes are as "Cheap as chips". Nonetheless, irritating as you now have to go off and arrange and wait for another order to arrive, when 1 could have been included in the original order. I sent a note to Thomann just to let them know.
Overall, it is a simple, easy to use spray in a compact bottle that will fit neatly into any kit box/bag and not take up too much room.
Update: After pointing out the missing brush to the staff at Thomann, they immediately resolved the issue (Within 2 days). Top quality after sales care as always from Thomann. Thanks guys!
