Quality, fitment, look. Great sound and love the type c plug. The pair was not a good match. It seals well. My son also looks cute in his new slides. I don?t wear high heels anymore, but these heels feel stable and confortable and I wear them to my ballroom dancing classes. All round a great buy and pleased i picked one up. Very spacious inside. My original review:Worn for some of everyday since purchase, mostly around the house and garden, occasional dog walks (with socks) and frequent, probably daily cycling trips. The mouse feels better when clicking, the RGB element looks better and brighter, and overall the entire mouse looks sleeker than the Deathadder did.
