Received this unit on time and it was packaged VERY Well. Came with everying in the description along with the users manual. I've never done any concrete countertop finishing before and have close to 300 square feet of freshly poured outdoor love to embrace over the next week or so.Started off on a test section (poured separate to the main counter), connected the hose, plugged it in and fired it up. Using this outdoors it is NOT very loud, sure you can hear the grinder working but at the time of this review I have been out there for about four hours total and have not had any problems at all with noise levels. No complaints from my wife, dogs, or neighbors :)Since I am using this to expose the aggregate and embedded fireglass I decided to start with another type of disc (Turbo Cup) for quicker removal of material until I get to the desired look we are after. This thing RIPS through the top with very little pressure and does a great job of leveling my otherwise less than professional original pour.So far I've only used this for Wet Grinding and the guard is actually doing a great job of keeping the water off me and dispersed in the direction of where the opeing is. SURE you get a small mist that is inevitable, but honestly all I have used so far is a pair of rubber boots and a disposable vynil dishwashing apron and there is nothing on me at all when I am done for the evening. Never once have I felt any kind of shock, hum, or buzz while using this device even without gloves. GFCI switch has worked as expected and have no fears of saftey.Got about 100sqft left with the initial grind then will be switching to the disc's that came with the unit, I'll follow up with an additional review once I have had a chance to use them.

This polisher works great as long as you polish flat. As soon as you polish an edge, you will run into problems!1) The water guard has no lock and is not rotatable/adjustable. This causes the guard to drop flat on the surface - which works fine when polishing flat, but when you turn the polisher to do an edge, the guard flops around and constantly gets in the way.2) When polishing on an edge, the body of the polisher gets wet. There are vent holes in the base of the tool near all of the wiring, and as soon as water goes in there you will get a minor shock and/or the GFI will trip until it dries out. Sometimes the polisher will not turn back on, even though the GFI isn't tripped. These vents probably aren't necessary since there are vents on the top edge for the gearbox and motor. I think a little more water proofing of the wiring and speed controller would have gone a long way.3) I took the body of the polisher apart 10 times in one day to dry it out so I could keep working. The way the wiring is routed inside the handle, some of the wires get squeezed and are chaffing. It only takes two screws to remove the plastic housing which is good, but I feel like a little more care could have been taken in routing/protection of the wires.4) The water hose is too short and the fitting leaks. Garden hoses are heaving and big, so the polisher comes with a small cord sized water hose with a garden hose fitting. The problem is that this hose is too short, so you are constantly pulling on the heavier garden hose while working. Another problem is that the brass hose fitting absolutely will not seal tight against the garden hose, so it sprays water through the fitting. Lots of fun when it's laying near the extension cord!Let's face it, wet polishing means mixing electricity and water - so wear rubber gloves, rubber soled shoes and (with this tool anyway) don't plan on wet polishing edges.I am going to try and dry polish my edges, which does work but causes a lot more wear and tear on the polishing pads.I also plan on spraying all of the wiring and speed controller with Never Wet to try and fix some of the shortcomings of the design.

I thought I purchased a Hardin HWV5GRIN if a HWV5GRIN is what is pictured on Amazon's website which shows brush caps and the water control at the head of the unit. I purchased this HWV5GRIN as a beginner to polish out my first concrete counter . Set for the polisher took less time than the plastic needed to control the water run off. The polisher was getting good results as it worked the surface of the counter. About six hours into the project the polisher's RPMs dropped to half. Not knowing why, I checked the rpm dial to see if it had changed - no change. I checked the GFCI - it hadn't tripped but I hit the test button then the reset the GFCI - the RPMs still were low. I thought maybe the polisher might have gotten hot so I let it set for about a half hour to cool - still didn't help the RPM problem. My next thought was the brushes, I go to check the brushes and that is when I realize I didn't receive the same polisher as pictured in Amazon's ad - which has brush caps in the body of the unit. I wrote Amazon, they responded quickly telling me they we're sorry and a replacement polisher was being sent out - very professional. I received the new polisher as they said but sadly it was the same polisher as the first - not as in the picture. I wrote Amazon again - they don't know what inventory issue they have so they asked me to return the second polisher and they will refund my money. I don't like writing bad reviews but you should know that currently the item in the picture for the HWV5GRIN is not what is being shipped out - hopefully Amazon will get it sorted out or change the picture.

I tried the chemicals for light etching in bath room marble-too much work. I bought this for the shower which was etched deeply, followed easy directions and great result. It is easy to use but noisy and tiring after a few hours. The machine makes quick work of the etching so that by the time your done with the first pad ap (we started with 1400) the result is very rewarding.The polisher will do all the etch work jobs, just pick the appropriate pad to start and always end up with 3000 for best result.We didn't use the water injection-partner with a spray bottle constantly applying water works fine.

This is exactly what we were looking for with our concrete countertop project. We started with the low grit, exposing the cement down to the aggregate so the natural colors of the exposed stone and fossils we inserted would pop. That was the longest grit to polish with, but we took off a lot. We moved up with a few runs over the top using each grit to 400, then used slurry to fill in any of the exposed holes or gaps due to our inexperience in concrete pouring, and laziness with shaking our molds. We then polished with each of the Hardin pads up to 1500, wow. Slick, shiny, one of the most impressive DIY's we've done. The mold building and concrete pouring were the hardest part of this project, and that was with average to above average carpentry skills. The Hardin polisher was a great tool for us having zero experience polishing. It was easy to use, and did a great job. The handle options are versatile, which we didn't think would matter, but in the end it did, just because of the location of our counter layout so we utilized both handle options. Great product! Now we're scheming for other projects.
