The red Sidekick in standard toughness has been an excellent match for an autistic, sensory-seeking, adult who predominantly chews with the extreme rear molars/"back teeth". The limbs provide a variety of shapes to explore and extensions that have enough length to reach rear teeth while still being relatively slim. Overall the item is smooth with minimal seams and the material feels high quality. Even with enthusiastic adult use, it appears to be extremely durable and shows NO signs of wear after several weeks. It is extremely easy to clean, as per the included instructions, using warm water and mild soap. The texture is relatively tough, which was a positive, satisfying experience in this use-case but could be a bit too much resistance/sensory feedback for a chewer looking for something less stiff. This particular figure could be a great match for chewers who are attracted to firm, rubbery textures like erasers, pencil grips, bendy toys, sandal straps, bath/pool toys etc. It fits perfectly in a plastic box originally intended for storing 4x6 photos, if a container for clean/safe-keeping is desired. The ordering process was simple and the delivery arrived promptly, within 3 days of purchase. Overall, the Sidekick has far exceeded expectations and we will definitely return to ARK for any future chew needs.
