For the money these are pretty good. I have purchased multiple sizes and am generally happy with them. The fit and finish is not a great others i have used or seen and I am doubtful they are single cast. The main issue i have is where the horns meet the main part of the bell. The paint rings are just touch smaller than the rest of the horn and leave a rough or sharp like edge around the horn. I dont notice it much but its a consistent flaw across the all bells that have and is more pronounced on some. Again for the money they are good value and feel nice in the hand. Not sure how they hold up if they are getting dropped or abused.
