The Beginner Pegging Set comes with a dildo that measures just as listed in the description. The total length is 6.5" with roughly 6.25" being insertable. The dildo measures at 3.75" in circumference. This is a decent beginner size. This set is also nice for beginners because as you and your partner grow comfortable with the strap on experience, you can switch out the dildo for a larger sized one. There are three different sized rings that come with this set allowing you quite a bit of flexibility in the dildo size.

The harness that comes with this set is very adjustable. I have a 31" waist and 41" hips with larger thighs. This harness fits me with so much extra room that I will probably trim the straps, so they are not hanging in the way. The straps also tighten a bit further than my measurements. If you are smaller than my size, I will warn you that the strap around the waist only tightens on one side so it can feel a little lopsided.

The harness in this Beginner Pegging Set is pretty comfortable but leaves a little to be desired. The adjustability makes it easy to fit correctly and make sure it is tight enough not to rub, but the straps aren't the most comfortable. I am a pretty bony person, so when the straps are tight enough to prevent rubbing, they dig into my hips. The plate piece where you attach the dildo is more comfortable than other harnesses at the same price point but can be a little uncomfortable when being rougher.

The dildo is a smooth silicone that is soft and simple. It has a little too much flexibility in my opinion, but that may be nice for someone who is new to the experience. There is a curve in the dildo that allows it to hit the G or P spot if you make sure the dildo is facing the correct direction in the harness.

Overall, this set works well. The harness stays tight enough and holds in the dildo well to make the play simple and enjoyable. I have not tried another dildo with this harness, but with the three different-sized rings, you should have quite a bit of flexibility with the dildo size.
