Does anyone know of a good commerical kit for the deglycosylation of proteins under non-denaturing conditions?

From my experience, the only one really working under non-denaturing conditions for moderate to highly glycosylated proteins is the EndoH kit from NEB!

The question sounds ambiguous. I suggest discriminating between enzymatic glycosylation and non-enzymatic glycosylation (glycation) of proteins. Means for deglycosylation in both cases are different.
