"This is an exact fit replacement of the bearings on my Harbor Freight 600lb boat trailer (Model #5002)."
"I watched an excellent video on YouTube for packing and removal/installation done by a Canadian (How to Replace Trailer Wheel Bearings-YouTube https://www.youtube.com/watch?v=z-q9QFRhLi4). Now, Amazon has the [Harbor Freight style] dust caps/covers (Tie Down Engineering (81167) 1.98" Hub Dust Cap, (Pack of 2)), which you probably want to replace."
"With a about 10,000 miles on trailer I didn't want to trust the original bearings on another road trip."
"I just received these bearings."
"Installed it on a trailer and went 2 hours away & picked up a v-strom motorcycle and drove home with no problems. I have hauled many motorcycles, atv's, loads of wood, debris from a house remodel."
"These bearings work great as replacements for a Harbor Freight Trailer."
"These things are beefy..unlike the garbage bearings that come on the harbor freight trailers."

"I had experience with a smaller, less powerful unit bought at CVS, but even that was helpful. (EBL 840 9V Battery Charger with 4 Pack 600mAh Li-ion Rechargeable 9 Volt Batteries). UPDATE Aug. 2017: I've used this unit for 4 months and it got me through a really horrible time where I was suffering from knotted shoulders and trapezius with terrible trigger points that were so bad I was unable to sleep on either shoulder for nearly 4 full months. UPDATE Sept. 2017: Well, unfortunately, the unit quit working a few days before I had to travel, so I was forced to buy another one to replace it. My original review was 5 stars, dropped to 3 while I waited for a refund, and am leaving it at 4 stars because the seller did take care of the issue and the new unit seems to be working fine (although I did just get it a month ago)."
"I get treated by my chiropractor every month with a professional TENS unit for Sciatic Nerve pain."
"This tens unit has just the right amount of power behind it, small size and features to make it a must have for those with MS, muscle or nerve pain. The housing isn't as nice as some of the higher-end commercial units, but the electrical configuration options are comparable. Sometimes I put it on low and just run it for 30 to 40 minutes while I read, work on the computer or watch tv. *It should be noted that this gizmo has decent power output and runs for a long time off of one 9v battery. The pads are comfortable--not overly sticky or gooey but nonetheless result in excellent adhesion. When finished just re-apply them to the sticker backing sheet they came with and reseal them in the envelope to extend the life of the pads."
"Tens units are the best when it comes to muscle pain."
"This is the second one of these to break within a month of use."
