I love Canson watercolour paper pads as they're always very decent quality, affordable and perfect to use as sketchbooks. I've been using this pad often, and the paper quality is good for mixed media, which is what I bought it for. I haven't used it with watercolours yet; mostly with acrylics paint, acrylic inks, crayons, pens, Posca ad Pitt Pen markers and it stands most things beautifully even without previous gesso priming. I love the pages micro-perforation as it allows me to use them as stand-alone sheets, or keep them as a pad.
On the flip side, this Montval series is more like a student pad, so worse paper quality than other Canson pads I own and also re the quality of the front and back covers, which is quite bad. Besides, the paper doesn't handle rubbing well, and sometimes the paper sands off if not primed. That being the case, now I gesso the pages that I intend to rub or scratch. I would not use this pad paper for professional purposes.
For the rest a good affordable study or student watercolour pad with decent quality paper.
