Rated 4.0 out of 5.0 by RMTW Great product, but don't expect it to be easy the first time
I'm a pro and we use this stuff when we're in a pinch. It's real simple with 1/2" hardibacker: Use the hardi-scissors or expect a hard time cutting it. You can use a circular saw but as others have mentioned, it's a dust bowl. Use a good screw gun or expect a hard time getting the screws flush. Proper shimming is also key with hardibacker. It gives you a really nice flat surface unlike old school concrete board which will bend with the studs and cause lippage on larger tile formats. For circle and interior cuts, a 4 1/2" angle grinder with a diamond blade will do everything you need.

Rated 4.0 out of 5.0 by Bill good value nice flat surface
I just did a 48x32x79 high shower, the jigsaw and circular saw w/ masonry blade worked well, utility knife hardly at all - I wasted at least 1/2 sheet trying, act accordingly. Maybe the scoring tool is a good $8 investment, I dinged it one star since it does not snap like in the video.
Hardibacker claims no moisture barrier needed, some building codes require a MB, a lot of discussion on message boards regarding MB or not. If this is a shower with a lot of use and/or in a humid climate I'd put a coat of RedGard on before tiling, bit I am no expert. I put 100% silicon between seams and where 2x4s were visible, no silicon where mortar was going

Rated 5.0 out of 5.0 by mtarallo Awesome Product - easy to use, heavy and sturdy
I used this material for a roof on top of my pergola. I know it is not to be used for outdoor applications (as per its warranty) however I did my research and have seen much success with it here in Florida's weather. I painted the interior side with exterior concrete paint 1 part expoxy (the ceiling) and the exposed side (roof) with a siliconized roof paint. Lanco 1-Gallon Ultra Siliconizer Roof Sealer - I sealed the joints with roofing tape. A waterproof seal and a nice finished look.

Rated 5.0 out of 5.0 by Jeremy Best Board in the Market
I have been in the industry for 35 years and I find this board to be the easiest to work with, strongest and best for mold and moisture. I tried all the other cement boards like Durock and Wonderboard, yet, those are messy, less than 50 % cement, hard to cut, and get mold through time. For all those out there, HB can be cut with a utility knife indoor - snap and score ( popping the board up instead of down like dry wall), you can hammer the board and it won't deteriorate, make sure to wet the board to get the best adhesion to tile, and put an additional layer of versabond to match the drywall. Holes are easy to perform as well. I GET 0 CALL BACKS WITH THIS BOARD and NO MOLD OVER THE LIFETIME OF MY INSTALLATION. BEST RETURN ON INVESTMENT FOR SECTION 8 BUILDERS CONCERN ABOUT MOLD.

Rated 5.0 out of 5.0 by wethead one of the best products I've run across ever
Just used for both floor and wall replacement in a 50 year old upstairs bathroom. Couldn't be easier to use. The 3'x5' size is perfect for many jobs, and not too much for one person to handle, even in tight confines.
Score and snap easily with a carbide tool - get one and save yourself a lot of trouble. Can be scored in a pinch with a razor, but that is a lot more work. Snapping off thin strips is a mechanical problem, either score both sides very deeply, or cut with a saw.
Cuts like cardboard with a jigsaw and carbide blade, but wear a good breather mask - the dust is truly awful - a health hazard. I even 'plunged' the jigsaw to start a circular cutout for the toilet drain without drilling a starter hole, because I'm that lazy. Edges can be dressed easily with a rasp, but again, the dust ...
No need to pre-drill or countersink screws - they make their own way in just fine, leaving just a little pile of dust behind. That makes a huge difference in the amount of work. Use the right screws for the job. Sunk a couple hundred of them for the whole project, and the board never chipped or cracked.
The old plywood floor was never too solid, and had some water damage that would have become serious if not treated. I screwed the plywood down tight onto the joists, and laid this 1/2" cement board over it with thinset and a lot more screws. The result is a new floor that is the most solid in the entire upstairs - you'd think it was a concrete slab. Perfect to tile over.
Both thinset and mastic stick to it like ... well ... glue. For the floor, I put the rough side up, thinking maybe the tiles would adhere that much better, while the smooth side is pinned down into the mortar below by all the screws.
As another reviewer noted, this board is not a true 1/2 inch thick, it is a bit thinner. The total additional height of the new floor plus ceramic tiles minus the old plastic tiles is about 3/4". Needed a taller toilet ring, and a hot-water heating baseboard had to be removed, modified, and then reinstalled higher, as well as all floor moldings replaced.
Approximately 33 square feet of flooring required about 20 pounds of thinset, mixed in 2 batches, and about 10 pounds of grout. I'm guessing I used about 200 screws, but when I realized I had way to many and couldn't return them, I overkilled that part of the job. I pity anyone that someday has to take this floor apart.
The company's installation video is terrific - watch it!

Rated 5.0 out of 5.0 by BackerBob Advantages and disadvantages.
Disadvantages. This product is hard to cut with a saw blade. Corners break off if it is dropped. Is less then 1/2 inch thick. Screw heads are hard to get flush with surface.
Advantages. Cuts as easily as cutting paper with scissors with snapper shears ($179 to $300) with no dust and reduces cutting time 10 fold. Works well over sub-floor with questionable deflection. I often use a thinned down mortar under the board for leveling, for stiffening up a bouncy floor or for extra bond strength. I've installed over 70 jobs and never had a tile failure. I use latex modified mortar. Also this product matches up well with 3/4 inch hardwood flooring at the transitions. Is less messy and easier to cut then wonder board when snapper shears are used. I use a tile drill bit to countersink screw holes and regular decking screws where a flush screw is required.

Rated 5.0 out of 5.0 by Jerry Easy to use, does the job well
I had previously used the other backer board and the quarter inch Hardie (for a floor) and chose this for a shower enclosure. I had no trouble scoring and snapping 3 pieces across the 36 inch dimension BUT I used the recommended carbide tip scoring tool. Maybe a heavy duty box cutter would do as well, but this is certainly not a task for those little snap blade razor knives. I used a mortar wheel on a roto tool for a small cut-out and it made quite a mess. Using a tile snipper worked much better for edge trims.
As for the dimension issue, I agree things should be called what they are (like lumber dimesions?) but I found the .42 inch thickness to be perfect for a tile job, as it allows for the adhesive thickness, otherwise the tiles would stick out too far. For a thin plastic sidewall job I can see where this would be a pain.
