The XR Spark is a slim prostate vibrator that adds electro-stimulation to the usual buzz, controlled from a wireless remote. With 4.1 inches to insert and a 1.4-inch widest point, it's the more compact choice among XR's e-stim plugs, made for people who like a manageable size but want more than plain vibration.
The plug tapers to a 1.4-inch widest diameter, then narrows to a 0.8-inch flexible neck before the flared base. That neck matters: the plug can shift slightly with your body instead of pressing on one spot, and the flare keeps it from travelling too far. Overall it's 4.7 inches long, so it's discreet enough to wear while you move around, and the base stays outside.
Vibration has four speeds and four patterns. E-stim has three levels and five patterns. XR designed the two to run independently, so you can let the vibration hum along while the e-stim pulses on its own rhythm, or use either one alone. At the low end the electro sensation feels warm and buzzy; at the top it's a sharp, muscle-tensing pulse. Work up slowly and give each step a minute.
Go to the toilet beforehand and lay a towel down. Warm the silicone in your hands, coat it in lube and insert it slowly while lying on your back with knees bent, or on your side. Leave the remote alone for a few minutes so your body relaxes around the plug. Then try the lowest vibration, followed by e-stim at level one, and keep the session short the first time. Breathing slowly and pushing out gently as you insert makes everything easier.
Keep e-stim below the waist. Don't use it with a pacemaker or other implanted device, with a heart condition, during pregnancy, or on irritated skin. Use a water-based lube or e-stim gel, which XR recommends, and apply enough to coat the plug evenly. If you feel stinging in one spot, stop and add lube.
The Spark suits someone who can already take a small plug comfortably and wants to try e-stim without a large toy. If you've never used anything anally, start with a non-electric plug from our prostate massagers and come back later. If you want a cock ring included, the Shockwave adds one; for a curved shape aimed more squarely at the prostate, see the Volt.
The Spark is rated IPX6. That covers sweat, lube and rinsing under a running tap, but it isn't a submersion rating, so keep it out of the bath. Wash with warm water and toy cleaner before and after each use, pat dry, and store it apart from other toys. The remote takes one AAA battery, not included.
