Query: Not very practical

Stand sits too low in normal-depth tub to allow enough clearance for all but small people. Works a little better with sliding side bars reversed downward into main tray such that the tray rises above the rim of the tub, but then there is nothing but the friction of the rubber sleeves from keeping the tray from dropping into the tub. Book stand doesn't adjust enough to accommodate comfortable reading while fully immersed. Book angle only works well when seated, not while laying down in tub. No mechanism for holding book open -- must have a hand on book at all times. In summary, it may work OK for someone quite small who doesn't want to read while laying down.
