The Camelbak Groove is designed to remove unpleasant tastes or smells from tap water, and it does just that. Instead of buying bottled water, you can fill the Camelbak up with tap water from almost anywhere, and it will taste clean.
This bottle won't leak if it tips over, or if you throw it in your bag. If the cap is screwed on properly, it does not let any water through. The straw won't let water spill out of it even when not in an upright position.
The integrated loop handle lets you carry it around comfortably in your hand, or you can attach it to your backpack with a carabiner. It also fits most cup holders. The bottle itself is sturdy, and it will survive most falls.
The filters used in this bottle are not reusable, so that means you will need to keep spending money on fresh filters. You might also need to carry a spare filter if you're not sure when your current one will expire, as it's difficult to keep track of their freshness.
Since you need to use the filter to drink water from the bottle, you need to use much more force to drink from it. Although this applies to all water bottles with filters, the Camelbak Groove is slightly easier to drink from than other similar bottles.
You don't have to worry about getting wet with this bottle, since it has a valve that keeps water from leaking out even when being swung around (as you swing your hands when running). To take a sip, just squeeze the bottle and the valve opens to let water pass through. For times when you are not using it, you can turn the valve to a locked position to be absolutely sure it won't leak in case it tips over or when you're holding it in your bag.
The Camelbak Quick Grip is lightweight, and holds more water than other handheld bottles, which makes for a good balance between the amount of weight you need to carry and the amount of water you can take with you in a single bottle. Many cheaper handheld bottles are also smaller, so you'd have to refill them more often, or plant water bottles along your route thereby interrupting your run more often.
This insulated bottle will keep your drink cool (or cold, if you add ice cubes) on a very hot day for about 3 hours, which is much longer than any non insulated bottle.
The strap that goes under your palm is padded for extra comfort, and the strap that goes over your palm is adjustable. This makes the bottle cling to your hand, instead of your hand having to cling to the bottle, thus avoiding cramps.
Most of your palm will be snug in the sleeve, but you might have to fidget for a while until you find a comfortable position for your thumb. There are indents on the bottle, supposedly for thumb placement, but it still takes some getting used to.
As with any handheld bottle, you will want to switch hands after a certain amount of time, which can be fidgety and interfere with your run. Some users have also reported that the strap becomes loose and needs adjusting every so often.
The sleeve has a rather small pouch for keys, gels, money or ID cards, but it is not nearly large enough to fit most smartphones. If you want to take your phone with you, you'd need to figure out another way of carrying it.
The lid on the Thermos Intak is easy to operate- it pops open at the push of a button. The mouthpiece has rounded edges and is just wide enough to make it easy to drink from it without huge gulps or suction sounds. The ergonomic shape of the bottle along with the grip makes it easy to lift up and carry. The simple construction of the lid means you would be able to drink other drinks as well, for example juice or ice coffee, without the risk of clogging up the inner mechanism.
The bottle itself is made from impact-resistant material, and will survive most falls. However, the lid itself is the weakest point in the whole design in terms of durability, so you will have to buy replacement lids sooner or later.
There is a silicone pad on the inside of the lid just over the mouthpiece, which seals it securely when you close the lid. It fits very snugly over the opening and does not leak even when held upside-down, or on its side. However, you do have to remember to close the lid for it to work.
The straightforward design of the lid makes it very easy to clean both the bottle and the lid by hand, or in the dishwasher. Some water bottles have an intricate mechanism for drinking, with a lot of small, hard to reach spots, but the Thermos Intak keeps it simple.
Since this is not an insulated bottle, condensation will make the surface of the bottle drip with water, especially if cold liquid is poured in on a hot day. This can make it a little harder to grip, and can also increase the chance of dropping the bottle.
This bottle has a rotating meter on the lid to help keep track of how many bottles you've emptied, and also an indicator of how much water is left in the bottle. This helps some people drink more water, as it can give a sense of achievement.
