Easy to use
As someone who knows nothing , this equipment was easy to use. I understood instructions and it worked well. Bought to use as battery keeps dying from lack of use. Have used it twice. Very happy with it. Efficient

Quite Slow and Expensive but Works Well.
Quite expensive for it's power rating and what it is, but is does a thorough job of charging and maintaining (sometimes) batteries with a 9-stage process. At 4A you can imagine this is not the quickest of chargers and it took an overnight charge to get my failing 70Ah EFB battery from 50% to 100%. Unfortunately the battery is too far gone now for this to rejuvenate it to any extent though. Upon first use, the display on mine misted-up for an hour or so so I would imagine these have been stored or manufactured in a relatively humid environment prior to shipping. Whether this will affect it long term I don't know. It comes complete with a both crocodile clips or secure connectors that can be left on the battery for easy regular charging. All in all a pretty good charger.

Would not maintain only charge & was used
Faulty. Charged but would not enter maintain mode even if batt volts went low <12.3. Box had been opened & dusty. Returned same day. Gave 5 star otherwise reviews get pushed low

Good value and operation.
Does what it says. Good value, recent updates means older model charging cables can not be used, minor issue I am sure cables will be available soon. Bought for motorcycle charging and trickle charging.

4A was perfectly adequate to charge my Range Rover battery
This is a well made charger that comes with both ring and clamp connectors and a decent amount of cable. Silent in operation, with compact dimensions. It has 2 operating modes - charge and maintain/condition (long term connection )- and is suitable for motorcycles and most cars. I’d say, as budget options go, this is a good choice. And I’d buy it again.

Good product!
Good charger, love the screen telling you the battery status. Brought a battery in thought was done for back to life. Works well!

very good charger, but wish it had one more feature.
This is a very good purchase, and charges the motorbike very well. I like the way it's rain proof, and you can hang it off the handlebars with the rotating clip, my only real gripe, (hence one star off) is that it doesn't show you the amount of amps it's pulling, which is nice to know when charging. but overall very pleased with product.
