Again, another toy that is the greatest design, shape and size with a crappy bullet. This would be so cool if it worked with a rumbling bullet. Anally, I would suggest this for more experienced users.

I'm unsure why this little curly sperm-looking bullet is called a sentinel. But if it was one, it'd be the kind in immaculate garb, with dozens of achievement medals, and perfect in just about every way... except it falls asleep on duty. With so much going for this cute little guy, it was downright surprising when it just didn't do it for me - at all. Perhaps with some tweaking, the sentinel version 2.0 could really be impressive.

Sentinel is a nice little vibrating plug that's a good size for people new to anal plugs and also for those who prefer the things in their butt to be smaller. The vibrator included is pretty strong, but its vibrations diffuse through the plug, making them a low hum when the plug is inside. Regardless, it's good for experimenting with anal vibrations. Sentinel is made of pure silicone meaning that it is a $40 plug that will last for a long time.

Overall disappointment, I would look elsewhere for vibrating prostate stimulation. Although made of high quality material, poor design factors make the toy very unpleasant.

This unique toy is designed for men & women to use. Soft vibrations help to ease in its girth. Since it's silicone it can be sterilized thoroughly and shared with a partner.
