Solid case that protects a skycaddie SX model well. Although sold as for the SX500/550 this case fitted the SX400 snugly holding the device ithout slipping but with a bit of extra room all round the sides. The carabiner clip is solid and sewn into the corner well but i will keep the case in my bag or boot of the car vs clipped to the bag as i feel its too bulky and will bang annoyingly when walking. I am a little surprised Skycaddie do not offer a slightly smaller case specifically for the SX400 but this is fine.
