Sturdiness: Good, just be careful with leg adjustment.Remote control: Not applicable, didn't come with one.Easy to use: I'd say yes, overall you can pull it out and adjust the legs and quickly fit the phone into the GripTight One mount with relative ease. Just take care in how you adjust the legs. Most of it is plastic. This is the smallest one of this style so it's uses are more limited. The railing I have it on in the photo is clearly too large for it to wrap itself around, so I added a little rubber bungee to keep it from rocking.I have had the product for about 2 months and had been using it almost every day. Overall I really like the tripod and it's use and it allowed me to take some long exposure photo's and time-lapse photos . I had it mostly attached to a wooden railing to take time-lapse footage over a 2 hour period. It remain stationary in most conditions other than heavy wind, which I wouldn't expect this tripod to overcome.I've used it also on uneven terrain( dirt, hills, grass, rocks, etc) and the ability to adjust the positioning of the legs and shift where the centre of weight of the phone is over the legs is very helpful.The product broke today as I was packing it away(2 months of near daily use) I heard a snap and one leg fell off. I would recommend moving the legs with intention and not too much force. They can separate without breaking as they are a friction cupped fit design that allows for the articulation of the joints. As a result they can 'pop' apart without breaking can be pushed back together. In this case it broke right at the main joint where all three meet and there is no further articulation there so the plastic snapped before the first join instead of coming apart at one of the joints. I wouldn't call this so much a fault of the product maybe just a weak point to be very considerate of. Me squeezing it was too much for that joint to take. I usually take care in how I'm folding it away and work with the joints. This time I had all three legs straight and I just gave them a squeeze to bring them more snuggly together and heard a snap. Too snuggly it seems! I may purchase another one, or maybe one of the bigger units which might be a bit more rugged and better suited for the location I'm using it and can hold this style of wooden railing better.The only other thing I noticed was the ball joint that holds the camera is becoming less stiff over time resulting in it not being able to hold the phone as straight if there is any degree of tilt involved. Which is Ok for levelled shots, but not if tilted up towards the sky. It may be a combination of the wearing out of the plastic and dirt and dust buildup. Keeping it clean may restore that stiffer movement.I have cleaned with just a rinse of tap water in the past to clean up that dirt/dust buildup. Maybe the manufactures provide some better care tips to help prevent or account for that.I have since attached the leg back on by wrapped some copper wire around all three legs near the top joint to do a quick fix so I can still use it with reduced leg reach. One of the leg joints broke during the process so one leg is now one joint shorter. Not ideal, but still useable!The GripTight ONE Mount that comes with the tripod worked will with my phone and will still be useable for other tripods.For Reference I was using with a Samsung S7 which is less than half the rated weight it supports.Dimensions 142.4 x 69.6 x 7.9 mm (5.61 x 2.74 x 0.31 in)Weight 152 g (5.36 oz)
