The set includes six different parts, and so I'll give my thoughts on each individually.

Ball Gag
This was the piece I was looking forward to the most in the whole set. I already owned a ball gag, a "beginners" one with a diameter of 2 inches, but due to having TMD - a disorder in my jaw joint - I find it hard to use for any extended periods of time. I couldn't find the measurements of the gag listed online so hoped this one would be smaller; it actually ended up being bigger.

If I had to guess, I'd put the diameter of this gag at roughly 2.5-3 inches. It's unusable for me with my jaw, unfortunately, but perhaps someone without any jaw-related ailments could use this gag just fine. The straps look very nice in their sleek, black leather-like polyurethane and the belt buckle-style clasp is easy to use.

Collar
The collar had a noticeable crease in it from where it was folded for packaging, but while wearing the collar, it was not a problem. I really liked this piece despite a few personal appearance issues. The pleather felt nice on my neck and wasn't constricting for my breathing or swallowing. The leash hooked to the collar is pretty plain, so there isn't much to comment on, but it appears to be well made, and it's nice that the clasp matches the hook on the collar and the other metal embellishments of the set.

Personal Warning: For those who may get a double chin when looking downwards, expect the collar to make this more prominent as it keeps the skin bunched up above the collar. This is a problem I had when wearing the collar, and I also noticed the unfortunate effect it had on making the slight hunch in my back/neck even more apparent.

Handcuffs
When not in use, the handcuffs appear to be not much more than stiff strips of pleather with Velcro straps. And that's essentially what they are, but when wrapped around my wrist they offered a great bondage aesthetic. The cuffs seem to have the strongest Velcro strips of the entire set, and the chain that attaches the two cuffs together is also rather sturdy. All-in-all, I'd say the cuffs are likely my favorite piece included in the Mistress Bondage Kit.

Blindfold
The blindfold is much too small. The eye pieces are barely large enough for full sight concealment, and I had to carefully position them and fasten the Velcro extremely tight in order to keep light from slipping in around the edges. And, with the Velcro being fastened like that, any movement of my head caused it to start to come unfastened.

If you can get it to stay on the right, the blindfold is the softest of the pieces in the set, with a soft padding on the side that touches your skin, and is comfortable to wear. While softer than the other pieces, it does seem to have a weaker Velcro strip.

Whip
The whip in this set is, to be more precise, a flogger. And this particular flogger would be a great toy for beginners to experiment with! The handle is the perfect size to sit comfortably in your hand, and the wound polyurethane has a wonderful aesthetic to it. There's a safety-loop to go around your wrist to keep it from flying off if it happens to slip from your grasp.

With a padding similar to the blindfold on one side of the tassels and black pleather on the other to match the rest of the set, the flogging end of the whip looks and feels very nice. A few light smacks along my arm and leg were enough to show the ends can give a nice sting in use, and I'm sure others who enjoy the pain could have a lot of fun testing out the different intensities of this sting with more forceful swings.

Tickler
The tickler in the set looks a little out of place with its shiny plastic handle amongst the pleather straps of the other pieces. It sort of resembles the workmanship of a children's toy, but it seems sturdy enough. The feathers are soft and came unruffled/undamaged, although they do all curve to one side.

Overall Impression
Considering how similar quality pieces sold individually could end up being $20 or more alone, the set is a great value to get everything together and matching. The only item in the entire set I think needs to be fixed is the too-small blindfold, while the other pieces are of good quality and may only have small things I take personal issue with.
