The shipping of this tester was really fast, received tester in 3 days to Hawaii. It came in a box and the box was packed well to prevent damage. Battery tester's quality is excellent! The tester is thick plastic, the cord does not retain memory when bending, and the battery clip open wide to make sure you have a good connection. The price of this tester is awesome!! It has many features for it's super low price. I have bought a lot of meters and testers in the past. Some only check voltage, a few is a percentage and voltage meter, and usually the load tester is separate. I would carry at least 3 meters to check voltage, load, and percentage. This BT500 can do all those tests and more. It is very simple to set up by connecting the red clip to the positive post and then the black clip to the negative post on your battery. It turns on and the displays show you your options. There are 3 lights to show you off hand your batteries condition. Green is good, yellow means you need to charge, and red is charge and if it can't be charged, it is time to get a new battery. You can verify the lights by going to the testing options. The menu is easy to follow. It will ask you 12 or 24 volts, what type of battery, and the cold cranking amps. The label on the battery has all this information. This tester will tell you the volts, amps, state of health, state of charge, and provide you with a waveform. You can have a tester that tells you your battery has 12 volts but that is meaning less. You need to put a load on the battery and if you have a weak battery with less then 10.5 volts, your car will have a hard time starting if it starts at all. the BT500 tester will also indicate how much your alternator is putting out. You usually need around 13 to 15 volts for your battery to be recharged. I really do not have anything negative to say about the tester itself because it is accurate, durable, and it does everything the company says it does. Very easy to use and very compact.Two things that does not affect my rating because it is not negative. One, I wish it came with a little plastic carrying case, but that is no problem because you can always find one. Two I wish it was touchscreen and that is not a problem because the buttons are marked clearly and is very easy to use. I have tried this tester on my boat, riding mower, motorcycles, and cars and trucks. What I found out on my outboard motor is that the motor has no rectifiers and parts to recharge the battery, and my riding mower had the ability to recharge the battery except when I flipped the mower over it lost its ability to recharge. Now I know exactly how long my boat battery will last before I leave the dock. Being stranded on the ocean due to a dead battery is no fun. All this time I thought my boat battery was being recharged when using the boat. This tester may have saved me from being stranded with a dead battery. I do not think this tester is waterproof so if you take it on your boat, make sure to keep it dry. I am impressed with all the features this tester has and what it can do.
