I'll be the dissenting opinion. Bought the set several years ago thinking I'd use them constantly because I do a lot of o ring and lip seal work. I found it hard to dig out tight fitting o rings with them not to mention the rubber soft grips become slick as goose **** when soaked in oil, ATF, hydraulic fluid ect.
Also the blades are rounded to prevend damage to the seal but are thick enough to damage the o ring groove on the part while digging out some seals.
I don't ever have any trouble with damaging seals and o rings with my pick assortment. They'll dig out any o ring or lip seal, even hardened ones.
I traded my set back on the Snap-On truck. Haven't even once thought, man I wish I still had those seal tools.
