Shiver Me Timber!

Pump it, stroke it and vibrate it, this is a multifunction pump that can work with the right amount of practice. I would suggest a smooth sleeve in addition to the textured sleeve it comes with and use the vibrations sparingly. Experiment with the stroker feature, plug the hole for a pump and shiver your timber!!
Great pump action.
Practice makes for better usage.
Hole in pump shaft for air release.
Need a different sleeve.
Vibrator only at the tip.
Rating by reviewer:
extremely useful review


This pump has all the bells and whistles!! Maybe too many. It took a bit of practice and my husband gave up a few times before we got the timing right. The stroker was easy to get going after practicing, getting your rhythm right and with no vibrations.

The pump was easy to figure out, worked well with the vibrations and remember, cover the hole with tape!! My husband loved using this solo and with me as a partner. I enjoyed playing with this on him and loved it when I got everything working right!! Watching him while I worked this was very sensual, as a matter of fact, it always ended with a climax!! (Okay, couldn't help myself!!)

Material / Texture

The pump shaft is smooth, clear, hard plastic. That has a safety rating of 8, is completely non-porous and is very rigid. The shaft has no texture which does very little for stimulation. There was no odor or taste to this part of the pump.

The TPR sleeve is nubbed inside and is very soft feeling, but kind of firm. There is some stretch to it, but not as much as we were expecting. (Our sleeve is purple since we did not purchase this at Edens, unfortunately we purchased this about a week before I discovered the site.) The sleeve has a safety rating of 6, it is semi-porous and is not recommended for sharing. There is a bit of a rubbery aroma and I am not sure if there was a taste to the sleeve. The internal nubs add some pleasure to the session, however, if you get too much suction they can be very uncomfortable. If used as a stroker instead of the pump, it can be pleasurable. I would also suggest a non-textured sleeve for pumping.

The pump bulb is silicone and so is the vibrator covering on the top, ours is also purple. This allows for easy gripping and controls. The pump bulb is larger than normal, very supple and actually works very well.
    • Light odor
    • Somewhat porous
    • Textured interior

Shape / Design / Size / Fit

The pump is a total of 13" tall, 2 1/2" diameter and has a usable internal length of about 10". There are one inch measurements in 1/2" increments on one side. The vibrator/handle is about 1 1/2" diameter and 3" tall. It flares to the shaft diameter and uses the silicone cover as a sealant. The sleeve is about 1" diameter, unstretched, and will stretch to accommodate about 2". My husband found it seriously uncomfortable. We purchased a larger, smooth sleeve for his use.

The pump bulb is huge, about 3 3/4" long and 2 3/4" diameter. It is attached directly to the shaft via a plastic connector. This worked very well, had plenty of suction power and was nicely supple. The vacuum release is a small, bead sized hole drilled directly into the plastic shaft. This made using the pump as a stroker fairly easy but did require tape over it for pump usage.

This is not a small toy and would not be one I would ever travel with, the size and lack of discretion deters me completely.

Functions / Performance / Controls

For use as a stroker, we would pump it two or three times, lift our finger off the hole and pump again. The vibrations were too much for my husband to deal with when stroking, but did work fairly well when he used it as a pump. Getting the right rhythm for the 'sucking' and stroking took quite a bit of practice and was easier when I pumped and controlled the vacuum for him. (Pretty fun for me, too!)

The vibrator has a short cord and uses 2 C batteries. The dial is on the front and turns for speed and intensity level. It was pretty easy to use, however you might need three hands to use it with the stroker!! We found the vibrator to be a bit noisy. The vibes were felt primarily in the tip, but some did escape down the shaft for his enjoyment.

The Grand Prix makes a good penis pump with vibrations if you purchase a smooth sleeve for comfort and fit. The internal texture of the nubbed one was too uncomfortable for pumping and enlargement. The size lasts until shortly after removal and we have not noticed any permanent enlargement. We use this for fun and his solo enjoyment, not as an enlarger.

We did not like the textured sleeve, but did use it as an occasional masturbator sleeve or to add to a bullet for massages. The hole in the pump is good for regulating the stroker, but when using it as a pump you do need to cover it with tape. This pump really needs someone with three hands. There is just too much to do with two hands.
    • Easy to use
    • Hard to figure out
    • Stimulating

Care and Maintenance

Remove the open ended sleeve, clean thoroughly in warm and soapy water, rinse well and let it air dry. It will trap any and all lint around!! I store this in a plastic zip lock bag and place it in the pump shaft for safe keeping.

We use a bottle brush and soapy water to clean the interior and wash the clear part with soapy water as well. The silicone top gets wiped with a clean, damp cloth. We rinse the inside and let it air dry as well. I do go back over it with a toy cleaner. We store the set in the cardboard box it came in. There is a plastic formed insert that stores the pump in its proper position.

Use water based lube only!! It is safe with the TPR and is also very easy to clean up after using. I do recommend using lube with this product, especially when using it as a stroker.
    • Easy to clean
    • Easy to store
Follow-up commentary
I got my husband a new pump with a trigger mechanism instead of the bulb and he likes that so much better. It is easier on our hands, we do not have to keep buying new bulbs due to cracking, (that is why I bought him a new one, the bulbs were getting horizontal cracks in them-2 replacements), and it was time for a change.

This does have some very good sensations and points, however, we are working on re-creating them with his new pump. Sorry, Grand Prix, you lost this one!!

    What kind of tape did you cover the hole with, just Scotch or duct tape or what? This sounds like a pretty versatile device. Thanks for the great review.

    Thanks for the review. We just got our first pump.
  • js250
    White bandage tape or small bit of duct tape works very well. Scotch tape does not.
