My favorite feature is the silky smooth texture because it really slides in and out easily - no tugging or pulling of the skin making it quite comfortable. The universal panties are difficult to work with and to really hold the toy in place, which is not unexpected with a one size fits most approach. We used a pair of strapless dildo panties made to size that worked perfectly. The vibration strength and patterns make it 5-stars for both partners. My wife didn't always orgasm during pegging; however, she loved every minute of use. What keeps it from being the perfect toy for pegging is the insertable length and the non-moveable angle of the dildo. We are not big people and we found it challenging to keep the toy inserted when thrusting because of the short length. The dildo for prostrate stimulation can only be used in the missionary position because of the direction of the curve and the location of the prostrate. That means in a doggies style thrust the prostrate is not being stimulated as much. With a curved strapless dildo, you can rotate the dildo so the curved end is still directly stimulating the prostrate in the doggie position. Overall the toy delivers.
