Well made, but be aware that dismenions are short 1/4 inch
I got the HDPE (High Density Polyethylene) Sheet, Opaque Off-White, Standard Tolerance, ASTM D4976-245, 0.375" Thickness, 12" Width, 24" Length and it's exactly what I needed for some table saw jigs miter slots that I will be making. Product is sturdy and feels very well made. The only downside, as others has pointed out is that the measurements are 1/4 inch short on all sides, so you dont get what you are paying for or described, but it still will suit my use.

******PERFECT FOR MAKING ROD LOCKER FISHING ROD HOLDERS FOR YOUR BASS BOAT******
I used these HDPE sheets to make custom fishing rod holders inside my rod locker box. I own a 96 Stratos bass boat that did not come with any kind of rod holders in the rod locker compartment. I found several pre-made rod holders on the internet but when I clicked on the price I nearly wet my pants.......cheapest one I found was $189.99 plus shipping!!!! I finally found an article on the internet the other day where another brilliant fisherman used material like a cutting board to make his own........and let me tell ya, it worked perfect and it looks professional {not some kinda mickey mouse crap}!! The one I made can hold 10 rods & reels without any of them getting a single scratch. I first used cardboard as a template then I traced my design on to the plastic material. A fine tooth jig saw blade cuts thru this stuff easy, but does take some time due to the precise angles. I put pieces of fuzzy Velcro where the butt of the rod sits along with short pieces of elastic cord. After securing this piece in my rod locker, I went to a local sporting goods store and purchased 10 golf club bag tubes. I had the perfect size circle door knob drill bit so that cutting part went faster. After securing the front section that holds the rod tips........I now have a custom rod locker organizer for a total cost of about $75.00 and that's figuring in any labor cost!! Saved ALOT of $$$$$$$$.

The thickness is very important to me
The thickness is very important to me I order 12"x24" x1" the majority of buyer complain of the size, you want a custom size than pay the price. The thickness was spot on 1 inch exactly. I always order bigger than I need saves me a lot of headache of reordering again. The item is excellent even if there is scratches I plane it down., Think of it this way when you but lumber does it come to the size that is stated,no. The seller to me is number one , very good product, fast shipping. I personally recommend this company I will be buy more item from this seller :)

Nice white plastic sheet.
I used this polyethylene (HDPE) sheet to make a base for yellow strobe that I magnetically attach to the top of my truck when I snowplow. The material was easy to cut and is ideal for outdoor use. I cannot say how resistant is would be to UV light in continuous outdoor use, but my application is only during snow storms, so it should last for years. Also at first I was skeptical that this product was polyethylene based on the feel and visual appearance (it was very shiny), but after accurately calculating the volume, measuring the weight with a precision scale and calculating the density it was a match for polyethylene (HDPE) and was not in the range for any other typical plastics like Polycarbonate (Lexan) or methyl methacrylate (Plexiglas), so don't judge a plastic sheet by its cover. I was considering a 5 star review since the following problems did not affect me, but like many other reviews the product is slightly less than a true 12"x12" and it does scratch easily. I assume the under size dimension is due to not accounting for the sawblade kerf during the cutting, so account for a slightly smaller size. Relative to the scratching, this material does scratch easily so if you are looking for a scratch free surface (which I was not) then look else ware. However if you are looking for a functional small (slighlty undersized) polyethylene sheet then this is the material you are looking for. It worked great for me.

Used as an extra Filler Plate for Chamber Vac
Purchased as a secondary insert in the Avid Armor GS53 Chamber Vac. Saves on vac time and keeps bags flat between sealing pads.

Exactly what I needed!!!
I bought this sheet of HDPE to fill the gap under a faucet and mounting block (see photos). The sheet was exactly as described. I used my Dremel US40-03 Ultra-Saw to cut 3" x 3" blocks. It cut just like a piece of wood. There was no melting. It was easy to sand the rough edges left by the cut. The holes I drilled in it were smooth.

Great to be able to get a small size for little project
If you haven't used HDPE before, this is the basic version of Starboard and the same material as a food grade cutting board. Cuts like soft wood and won't easily gum up a saw if you take the speed slow. The material was delivered flat and undamaged. As long as I can get a small piece at a reasonable price, I won't bother buying a full sheet to store the remainder.

Durable and well finished sheeting
Needed some tough material to replace a rudder board on a petal boat. This material was available in the right dimensions and thickness to minimize the cutting necessary to duplicate the previous rudder's shape. It wasn't absolutely flat but with a little heating from a heat gun, it was trued up for the application. The cut edges cleaned up nicely with a simple wood planer to allow rounding of the edges for "optimum" aerodynamics.
