As with most of the reviews (wish I had read before) poor quality caps leak all time

It's a good size and the only fault is that you have to really turn the caps to seal the water.

Rubbish, not well made, leaks water. Wish I'd never bought it.

Very good product

Really robust and smart looking. Our pump cover for the insert opening is too small for the generous aperture but we will work round that.

I wish I read the reviews before buying. Looking now it is quite clear there is a manufacturing fault with the caps.
Go Outdoors don’t read the reviews and don’t seem to care.

Had to take it back to go outdoors caps leak and wen tighten up you can pull the cap off very poor sort it out go outdoors as the container itself is quite good

Great container but the caps leak you need a belt to tighten the caps

Well there I was needing a standby water barrel to go with my existing Aquaroll... do I get another matching one or do I try the alternative, WaterHog ??? Well I finally gave in and thought I'd try WaterHog, mainly due to the much lower price, almost half the cost when on special offer and quite a lot more capacity. I liked the foam handle cover and ease of getting the handle on to the barrel, as well as large caps and stable to pull. Downsides were not quite as good quality, not so much ground clearance, a tyre slipped off once but not happened again since, sometimes have trouble with caps leaking and it can be hard doing these up tight enough as they use stickier silicone rubber seals (Aquaroll use rubber which have more give). The handle ends which connect to the barrel have a bit of play in them and could potentially pop off on a tight turn, however they are much easier to get on to the locating spigots than Aquaroll. Both types have top and side caps so can be tipped up, or I prefer to fill on it's side as that's much easier than taking the handle off, tipping it up then back down again when full. I did have problems getting the dust cover of my Whale pump/suction hose to fit the larger cap holes and either have to leave it loose on top or shove it half in/half out of the cap hole. You don't get any cap retaining straps like with Aquaroll, although these can get in the way when emptying etc. One downside of Aquaroll is replacement parts and accessories can be quite expensive, however I'm not even sure what if any spares are available for WaterHog. So the answer to the original question - still not sure, it's definitely a "six of one, half dozen of the other" scenario. If you want good value and/or more water capacity then WaterHog is the one for you! If you want best quality and don't mind paying the price, or are a bit of an Aquaroll (and WasteMaster) purist, as I was, then go for Aquaroll.

We purchased a Waterhog to take to a music festival in our motorhome as we were in a group of seven. The price seemed a bargain, but on filling the item for the first time, the outside filler cap leaked uncontrollably when being rolled away from the water supply!
Further investigation showed that the moulding of the main barrel was VERY rough on both of the filling points so a long time was spend with a sharp knife to remove the poor moulding and make the mating surface flat.
Be ready for some DIY if you purchase this item.

Using for the fist time, and seems ok. We have only filled it twice in 5 days which is much better than the old 27Lt one.
