Query: used to think harbinger made quality products

I bought these gloves because I currently have some of the big grip gloves with wrist strap, and wanted gloves that would be more flexible. The first day I used these gloves one of the grips started becoming unstitched! The pad was halfway off the first day of training in less than 30 minutes! I am also not impressed with harbinger since the last time I bought the "top of the line" big grip gloves, within the first couple weeks the seam stitches were coming undone on the right hand glove. However they do make comfortable and very intuitive gloves, but lack quality construction.
