The competition to develop the best all-round tennis ball machine is hotter than ever. In recent years Tennis Tutor have introduced the Tennis Tower Professional Player and Tennis Tutor Plus Player, both these machine offer 3 pre-set modes or drills which enable users to practice specific shots based on their  playing ability. However more recently Lobster have raised their game with the introduction of the Lobster Elite Grandslam 4 and Lobster Elite Grandslam 5, offering 3 and 6 pre-set drill respectively. Rather than based on level of play the Grandslam 4 pre-set drills enable users to practice against a specific style of play, for example the  ‘Grinder mode’ which will produce  a sequence of 6 slow high bouncing balls, to either forehand or backhand. The Grandslam 5 takes this concept further with the option of a ‘Approach’,  ‘Attack/Defend’ and Forehand Plus’ modes. The latest offering from Lobster is the Lobster the Elite Grandslam 5 SE which, as well as offering 6 pre-set drill allows users to customise their own drills and program these into the machine.
