Strong sturdy flask and not too heavy when full up. Tough enough to withstand my husband’s type of work and the contents stay hot for ages.
This is an excellent heat-holding flask, as you’d expect from this brand. My coffee was still hot enough after 11 hours which is pretty impressive. It’s a little large perhaps but perfect for a family picnic or even the solo traveller who won’t be able to access a kettle or cafe for several hours. It would also be handy if you knew you would be without power in the house for a while and wanted to keep a supply of hot water to hand. The cup is excellent, it’s so wide you could easily use it as a soup bowl. The handle is very comfortable to hold and the flask as a whole looks and feels balanced, a pleasing, if simple, design.
I have tried most flasks as being a football dad means standing in the cold a lot . However because it is completely sealed then no liquid can get inside the housing so it does not fail like other metal based flasks. Being metal also means dropping it does not mean smashing it so again it scores again. Hot liquid like coffee/tea/soup stays ‘drinkable’ hot for about 12 hrs, but even after this time whilst it does not go cold, some may find it below likeable drinking temperature but other s may find it fine. Bear in mind that most times you would not be keeping it hot past 12 hrs anyway. Scores 9/10 for me which is a score i do not give very often. Here are the specifications for the Thermos Hercules Stainless Steel Flask:
- Thermos vacuum insulation technology for maximum temperature retention; keeps hot for 24 hours and cold for 24 hours
- Rugged plastic outer shell and durable stainless steel interior with extra large cup
- Twist and pour stopper allows you to pour without removing the stopper
- Floats in water even when full
- 5 year guarantee
Absolutely love this item,has saved me a fortune at work as we have to pay for very small cups of coffee at extortionate prices,keeps my drinks hot all day from 6am – 5pm.
Having used various flask’s for a few years at work and now retired, i needed a new one for taking with me for picnics and day trips out. This is the best one i have used for this purpose and keeps the water hot all day even if you don’t always prefill it with hot water as recommended. A smaller cheaper flask that i prefilled first didnt keep the water hot enough even for coffee as this thermos that was not prefilled. If you have the time it is always best to prefill it for a few mins while you reboil some more water.
Reviews from purchasers :
- Best flask we have owned!
- You’ve tried the rest now try the best
- This flask was brilliant – kept hot for the whole of his day
Strong non breakable and keeps drinks really hot.
This is a great thermos, which really keeps your tea hot. It is quite big and heavy though, but we do like it.
I work outdoors & need to keep warm this flask is great, large & lasts me all day, i have no complaints with it & its easy to clean too.
Great flask keeps warm all day.
Absolutely superb at keeping soup hot all day (and i do mean from very early morning until late st night) , the strength of this was unintentionally proven by being accidentally dropped down a flight of concrete stairs when full. No damage to the all important internal vacuum flask and only the slightest of grazes to the hard wearing plastic outer casing. The only thing we miss is a handle to the screw lid/cup but that really is a very minor issue. The cup itself is comfortable to hold. Haven’t tested the fladk’scsbility to float ( not sure to be honest when i would use that) but, even ignoring that feature, this is a very impressive flask with a good capacity.
Ideal flask for a truck driver.
Heat retention is excellent, nothing else matters to me.
Very strong flask keeps hot for hours.
Keeps water hot for 24 hours.
I fill the flask the night before with boiling water to warm the flask. Then discard this, add fresh boiling waterin the morning & the water remains hot all day long – only flask we have owned to actually fulfil this taskwe now own 2.
A well designed flash can pour a drink while on a bus and drink it without spilling a drop.
Have purchased two of these, one purchased from another supplier for coffee while i am running a market stall with my other half. When i have placed coffee in the flask at 5am the final dregs are still piping hot at 2pm in the afternoon even though i have been drinking cups all morning and the outdoor tempratures on occasion have been close to 0c. With this in mind i had been searching for a food flask and had purchased various to find they were pretty well useless, none managed to keep the food hot for long periods even when boasting 8-10 hours. Most failed to keep food warm period.Ultimately purchased hercules flask number two for use as a food flask, obviously it is not as good as a coventional food flask as you can’t eat food directly from the flask, so it limits what food you can use it for, but as i normally have some form of soup for lunch when on the market stall, this is not a major issue, just means for chunky soups the early cups are more liquid and the last ones are more chunks than soup. Not perfect i know, but it does result in mouth scaldingly hot food being available 6 or seven hours after being placed in the flask. With this in mind it would probably work fairly well with things like pasta in sauce or rice dishes as long as the chunks are not too big. Just for information with both flasks we fill them with boiling water and leave them standing to warm up for 15-30 minutes before placing the boiling coffee/soup in them, as would be the requirement for any flask, for effective operation. (hot water not wasted, does the washing up)not tested the flasks ability to float but they have been dropped/knocked of tables on to concrete paving with no more than minor scratches resulting. In summary this flask is well worth the money.
I purchased this flask for my husband – a market trader who has been through hundreds and complains they dont last after a few months. This flask was brilliant – kept hot for the whole of his day. The only problem is the cup on the top. He says that when its a windy day it can blow over when full of tea.This is a small design fault and would deter me from buying it – but if the cup was a as big on the rim as on the top then it would be perfect.
This flask was purchased as a gift – it has been well received and as the item was purchased for an outdoor individual – it is a must have for those who like the outdoor. Drink is kept hot or cold as described.
Not the best looking thermos on the market, the design is actually quite effective. The plastic protects the flask from damage, and the bulk allows it to float if for some reason you are using it on water. Despite the industrial looks it is actually surprisingly light, and the thick handle is comfortable to hold even while wearing work gloves. It has flat spots on the side opposite the handle which prevent it rolling away if stored on its side. In use it is simply amazing. At 1 pm i pre-warmed the flask for ten minutes before filling with coffee, which i made with real milk. Drinking half a cup of water every hour or so the coffee was still too hot to gulp at half ten at night. The only thing i would have improved would be the colour. If you are making a flask to use where there is a danger of it floating away then i would have made it in a brighter colour so that if it does fall in it isn’t camouflaged.
Keeps drinks hot for ages on the coldest winters days specially if you heat it with boiling water and pour away first. It’s tough and durable, just the job.
