Some complaints about Rhino spray-in bed liners include general installation complaints, a duller appearance that does not match bed contours and lack of tear resistance. An important distinction is that a Rhino installation depends largely on the installers and each one may do it differently.
The main competition to Rhino bed liners is Line-X. Comparatively, Line-X liners tend to be thinner and more fitted to the truck bed, which helps keep the factory appearance. However, the thinner liner is also harder, which makes it more uncomfortable on knees and potentially damaging to some fragile cargo. The thicker Rhino liner is softer and has a sound dampening effect.
