Very Impressed
Received exactly what was ordered. More impressive was the thank you note and little mustache for fun. All items better quality than expected. I highly recommend this seller and their product.

Does the job, but clearly a low-budget item
This compass does the job of a compass and does it very well. They even throw in some extra lead and a little storage pouch too! But while it does its job well, it doesn’t really scream “quality” at all. A big disappointment was when I first saw it and noticed it’s painted. Not anodized or coated, it’s paint and it’s obviously paint, with small lumps and uneven spots. In my opinion it doesn’t look much like the images other than in shape, with the color not looking close at all. The other point against: the adjustment screw is not centered between the arms. If set as wide as possible this is very obvious and is likely limiting the total amount of adjustment. It’s certainly not a professional-level product but then again it’s not a professional-level price either. It’ll draw a circle or an arc, help you measure things, and even scribe some things like I have, but it won’t win any awards for build quality.

Economical Yet Functional
This is not a professional quality tool and is limited on the min/max width. It's an economical tool that does what it's supposed to do. It doesn't lock, strictly speaking, but the adjustment wheel is firm enough. It comes with 10-15 replacement leads. Comically, two of the three little vials containing lead were empty and their contents were rolling around in the little bag. One of them still had the cap on it, so I have to think the person packing it was all out of effs to give that day and just dumped the required number of parts in the bag instead of trying to fix it. Two steel tip replacements, two little tightening wheel replacements and strangely no little screw replacements. A mustache sticker and a hand-written thank you note. It's stable enough for what I need to use it for. Doesn't have as much flex as some folks have reported. But if you're looking for a tool with tight tolerances and high production value for architecture or engineering use, go spend $100 - 200+ on a different product.

Art compass
Works to make various perfect circles. I use it for art, i.e. color wheels, etc.

Great value for the money
I am always impressed with merchandise from Mr. Pen. As usual, this compass, fits my need perfectly. The addition of the extra pencil leads and the life time lead replacement is a bonus. Its compact size and the ability to make up to an 8 inch circle gives me the flexibility I need. It works well.

Open Carefully
Good value for the money. One thing though, open the package carefully. Unknown to me one of the tiniest of screws (and nut) holding the needle in place on the compass body worked themselves loose in the package sometime before I received it. Upon opening something fell out of the package onto the carpeted floor. No idea what fell out until I looked carefully at the compass and noticed that the tiny screw holding the needle in place was missing (the nut was still in the package). Luckily I had a large magnet in the garage and was able to use it to find the missing screw with it. On a side note though the compass comes with 2 extra screws and nuts just in case you lose one but I didn't want to start out missing a piece on a brand new tool.

Buy a higher quality one to avoid my woes
Kinda cheaply made, the color chipping a little, rough edges. The wheels that hold the tips is weak. If you're very light handed this can work before you, but I often found myself having to recalibrate the distance of the points.
