hard to keep attachment in the right place and locked on [SEP] i keep having issues with the attachment turning when i am using it making it difficult to aim at the correct teeth gum then when i try to carefully focus on it the attachment pops off this is bulky and i was okay with that because i know it needs the room for a decent amount if water but issues with the attachments spinning and popping off consistently is super annoying and not working may need to return i am not sure if it is just this one or the model in general
